AUTHORS MESSAGE RECENT
==================================================================RECENT
THE REPORT DESCRIBED ABOVE IS THE LATEST PUBLISHED DOCUMENTATION RECENT
FOR THIS PROGRAM. HOWEVER, THE COMMENTS BELOW SHOULD BE CONSIDEREDRECENT
THE LATEST DOCUMENTATION INCLUDING ALL RECENT IMPROVEMENTS. PLEASERECENT
READ ALL OF THESE COMMENTS BEFORE IMPLEMENTATION, PARTICULARLY RECENT
THE COMMENTS CONCERNING MACHINE DEPENDENT CODING. RECENT
RECENT
AT THE PRESENT TIME WE ARE ATTEMPTING TO DEVELOP A SET OF COMPUTERRECENT
INDEPENDENT PROGRAMS THAT CAN EASILY BE IMPLEMENTED ON ANY ONE RECENT
OF A WIDE VARIETY OF COMPUTERS. IN ORDER TO ASSIST IN THIS PROJECTRECENT
IT WOULD BE APPECIATED IF YOU WOULD NOTIFY THE AUTHOR OF ANY RECENT
COMPILER DIAGNOSTICS, OPERATING PROBLEMS OR SUGGESTIONS ON HOW TO RECENT
IMPROVE THIS PROGRAM. HOPEFULLY, IN THIS WAY FUTURE VERSIONS OF RECENT
THIS PROGRAM WILL BE COMPLETELY COMPATIBLE FOR USE ON YOUR RECENT
COMPUTER. RECENT
RECENT
PURPOSE RECENT
==================================================================RECENT
THIS PROGRAM IS DESIGNED TO RECONSTRUCT THE RESONANCE CONTRIBUTIONRECENT
TO THE CROSS SECTION IN LINEARLY INTERPOLABLE FORM, ADD IN ANY RECENT
LINEARLY INTERPOLABLE BACKGROUND CROSS SECTION AND OUTPUT THE RECENT
RESULT IN THE ENDF/B FORMAT. THE CROSS SECTIONS OUTPUT BY THIS RECENT
PROGRAM WILL BE LINEARLY INTERPOLABLE OVER THE ENTIRE ENERGY RANGERECENT
RECENT
THE RESONANCE CONTRIBUTION IS CALCULATED FOR TOTAL (MT=1), RECENT
ELASTIC (MT=2), CAPTURE (MT=102) AND FISSION (MT=18), ADDED RECENT
TO THE BACKGROUND (IF ANY) AND OUTPUT. IN ADDITION, IF THERE RECENT
IS A FIRST CHANCE FISSION (MT=19) BACKGROUND PRESENT THE RESONANCERECENT
CONTRIBUTION OF FISSION WILL BE ADDED TO THE BACKGROUND AND RECENT
OUTPUT. IF THERE IS NO FIRST CHANCE FISSION (MT=19) BACKGROUND RECENT
PRESENT THE PROGRAM WILL NOT OUTPUT MT=19. RECENT
RECENT
IN THE FOLLOWING FOR SIMPLICITY THE ENDF/B TERMINOLOGY--ENDF/B RECENT
TAPE--WILL BE USED. IN FACT THE ACTUAL MEDIUM MAY BE TAPE, CARDS, RECENT
DISK OR ANY OTHER MEDIUM. RECENT
RECENT
PROCESSING DATA IN THE ENDF/B-6 FORMAT RECENT
==================================================================RECENT
IT HAS NOW BEEN CONFIRMED (PRIVATE COMMUNICATION, CHARLES DUNFORD,RECENT
APRIL, 1991) THAT THE PROPER PROCEDURE TO FOLLOW WHEN THERE ARE RECENT
MISSING OR DUPLICATE J VALUES IS TO IN ALL CASES ADD A SEQUENCE RECENT
WITH NO RESONANCES TO ACCOUNT FOR THE CONTRIBUTION OF THE SEQUENCERECENT
TO THE POTENTIAL SCATTERING CROSS SECTION. RECENT
RECENT
THIS IS THE PROCEDURE WHICH WAS FOLLOWED BY ALL VERSIONS OF RECENTRECENT
SINCE 86-3 AND WILL CONTINUE TO BE THE PROCEDURE. RECENT
RECENT
INPUT ENDF/B FORMAT AND CONVENTIONS RECENT
==================================================================RECENT
ENDF/B FORMAT RECENT
------------- RECENT
THIS PROGRAM ONLY USES THE ENDF/B BCD OR LINE IMAGE FORMAT (AS RECENT
OPPOSED TO THE BINARY FORMAT) AND CAN HANDLE DATA IN ANY VERSION RECENT
OF THE ENDF/B FORMAT (I.E., ENDF/B-1, 2, 3, 4, 5, 6 FORMAT). RECENT
RECENT
IT IS ASSUMED THAT THE DATA IS CORRECTLY CODED IN THE ENDF/B RECENT
FORMAT AND NO ERROR CHECKING IS PERFORMED. IN PARTICULAR IT IS RECENT
ASSUMED THAT THE MAT, MF AND MT ON EACH LINE IS CORRECT. SEQUENCE RECENT
NUMBERS (COLUMNS 76-80) ARE IGNORED ON INPUT, BUT WILL BE RECENT
CORRECTLY OUTPUT ON ALL CARDS. THE FORMAT OF SECTION MF=1, MT=451 RECENT
AND ALL SECTIONS OF MF=2 AND 3 MUST BE CORRECT. THE PROGRAM COPIESRECENT
ALL OTHER SECTION OF DATA AS HOLLERITH AND AS SUCH IS INSENSITIVE RECENT
TO THE CORRECTNESS OR INCORRECTNESS OF ALL OTHER SECTIONS. RECENT
RECENT
ENDF/B FORMAT VERSION RECENT
--------------------- RECENT
THE FORMATS AND CONVENTIONS FOR READING AND INTERPRETING THE DATA RECENT
VARIES FROM ONE VERSION OF ENDF/B TO THE NEXT. HOWEVER, IF THE RECENT
HOLLERITH SECTION (MF=1, MT=451) IS PRESENT IT IS POSSIBLE FOR RECENT
THIS PROGRAM TO DISTINGUISH BETWEEN DATA IN THE ENDF/B-4, 5 AND RECENT
6 FORMATS AND TO USE THE APPROPRIATE CONVENTIONS FOR EACH RECENT
ENDF/B VERSION (SEE, SUBROUTINE FILE1 FOR A DESCRIPTION OF HOW RECENT
THIS IS DONE). IF THE HOLLERITH SECTION IS NOT PRESENT THE RECENT
PROGRAM WILL ASSUME THE DATA IS IN THE ENDF/B-6 FORMAT AND USE RECENT
ALL CONVENTIONS APPROPRIATE TO ENDF/B-V. USERS ARE ENCOURAGED TO RECENT
INSURE THAT THE HOLLERITH SECTION (MF=1, MT=451) IS PRESENT IN RECENT
ALL EVALUATIONS. RECENT
RECENT
INPUT OF ENERGIES RECENT
----------------- RECENT
ALL ENERGIES ARE READ IN DOUBLE PRECISION (BY SPECIAL FORTRAN I/O RECENT
ROUTINES) AND ARE TREATED IN DOUBLE PRECISION IN ALL CALCULATIONS.RECENT
RECENT
OUTPUT ENDF/B FORMAT AND CONVENTIONS RECENT
==================================================================RECENT
CONTENTS OF OUTPUT RECENT
------------------ RECENT
ENTIRE EVALUATIONS ARE OUTPUT, NOT JUST THE RECONSTRUCTED FILE RECENT
3 CROSS SECTIONS, E.G. ANGULAR AND ENERGY DISTRIBUTIONS ARE RECENT
ALSO INCLUDED. RECENT
RECENT
DOCUMENTATION RECENT
------------- RECENT
THE FACT THAT THIS PROGRAM HAS OPERATED ON THE DATA IS DOCUMENTED RECENT
BY THE ADDITION OF COMMENT CARDS AT THE END OF EACH HOLLERITH RECENT
SECTION IN THE FORM RECENT
RECENT
***************** RECENT (VERSION 2021-1) *************** RECENT
RESONANCE CONTRIBUTION RECONSTRUCTED TO WITHIN 0.100 PER-CENT RECENT
COMBINED DATA NOT THINNED (ALL RESONANCE + BACKGROUND DATA KEPT) RECENT
RECENT
THE ORDER OF ALL SIMILAR COMMENTS (FROM LINEAR, SIGMA1 AND GROUPY)RECENT
REPRESENTS A COMPLETE HISTORY OF ALL OPERATIONS PERFORMED ON RECENT
THE DATA, INCLUDING WHICH VERSION OF EACH PROGRAM WAS USED. RECENT
RECENT
THESE COMMENT CARDS ARE ONLY ADDED TO EXISTING HOLLERITH SECTIONS,RECENT
I.E., THIS PROGRAM WILL NOT CREATE A HOLLERITH SECTION. THE FORMATRECENT
OF THE HOLLERITH SECTION IN ENDF/B-5 DIFFERS FROM THE THAT OF RECENT
EARLIER VERSIONS OF ENDF/B. BY READING AN EXISTING MF=1, MT=451 RECENT
IT IS POSSIBLE FOR THIS PROGRAM TO DETERMINE WHICH VERSION OF RECENT
THE ENDF/B FORMAT THE DATA IS IN. WITHOUT HAVING A SECTION OF RECENT
MF=1, MT=451 PRESENT IT IS IMPOSSIBLE FOR THIS PROGRAM TO RECENT
DETERMINE WHICH VERSION OF THE ENDF/B FORMAT THE DATA IS IN, AND RECENT
AS SUCH IT IS IMPOSSIBLE FOR THE PROGRAM TO DETERMINE WHAT FORMAT RECENT
SHOULD BE USED TO CREATE A HOLLERITH SECTION. RECENT
RECENT
REACTION INDEX RECENT
-------------- RECENT
THIS PROGRAM DOES NOT USE THE REACTION INDEX WHICH IS GIVEN IN RECENT
SECTION MF=1, MT=451 OF EACH EVALUATION. RECENT
RECENT
THIS PROGRAM DOES NOT UPDATE THE REACTION INDEX IN MF=1, MT=451. RECENT
THIS CONVENTION HAS BEEN ADOPTED BECAUSE MOST USERS DO NOT RECENT
REQUIRE A CORRECT REACTION INDEX FOR THEIR APPLICATIONS AND IT WASRECENT
NOT CONSIDERED WORTHWHILE TO INCLUDE THE OVERHEAD OF CONSTRUCTING RECENT
A CORRECT REACTION INDEX IN THIS PROGRAM. HOWEVER, IF YOU REQUIRE RECENT
A REACTION INDEX FOR YOUR APPLICATIONS, AFTER RUNNING THIS PROGRAMRECENT
YOU MAY USE PROGRAM DICTIN TO CREATE A CORRECT REACTION INDEX. RECENT
RECENT
OUTPUT FORMAT OF ENERGIES RECENT
------------------------- RECENT
IN THIS VERSION OF RECENT ALL FILE 3 ENERGIES WILL BE OUTPUT IN RECENT
F (INSTEAD OF E) FORMAT IN ORDER TO ALLOW ENERGIES TO BE WRITTEN RECENT
WITH UP TO 9 DIGITS OF ACCURACY. IN PREVIOUS VERSIONS THIS WAS AN RECENT
OUTPUT OPTION. HOWEVER USE OF THIS OPTION TO COMPARE THE RESULTS RECENT
OF ENERGIES WRITTEN IN THE NORMAL ENDF/B CONVENTION OF 6 DIGITS RECENT
TO THE 9 DIGIT OUTPUT FROM THIS PROGRAM DEMONSTRATED THAT FAILURE RECENT
TO USE THE 9 DIGIT OUTPUT CAN LEAD TO LARGE ERRORS IN THE DATA RECENT
JUST DUE TO TRANSLATION OF ENERGIES FROM THEIR INTERNAL (BINARY) RECENT
REPRESENTATION TO THE ENDF/B FORMAT. RECENT
RECENT
ACCURACY OF ENERGY RECENT
------------------ RECENT
IN ORDER TO ALLOW ENERGIES TO BE ACCURATELY OUTPUT TO 9 DIGITS RECENT
ON SHORT WORD LENGTH COMPUTERS (E.G. IBM) ALL ENERGIES AND RECENT
ENERGY DEPENDENT TERMS ARE READ AND TREATED IN DOUBLE PRECISION. RECENT
RECENT
OUTPUT OF RESONANCE PARAMETERS RECENT
------------------------------ RECENT
A SPECIAL CONVENTION HAS BEEN INTRODUCED REGARDING RESONANCE RECENT
PARAMETERS. IN ORDER TO ALLOW THE USER TO DOPPLER BROADEN AND/OR RECENT
SELF-SHIELD CROSS SECTIONS THE RESONANCE PARAMETERS ARE ALSO RECENT
INCLUDED IN THE OUTPUT WITH THE EVALUATION. IN ORDER TO AVOID THE RECENT
POSSIBILITY OF ADDING THE RESONANCE CONTRIBUTION A SECOND TIME RECENT
TWO CONVENTIONS HAVE BEEN ADOPTED TO INDICATE THAT THE RESONANCE RECENT
CONTRIBUTION HAS ALREADY BEEN ADDED TO THE FILE 3 CROSS SECTIONS, RECENT
RECENT
(1) WHEN THE DATA IS PROCESSED BY THIS PROGRAM LRP (IN MF=1, RECENT
MT=451) IS SET EQUAL TO 2. THIS IS A CONVENTION WHICH HAS BEEN RECENT
ADOPTED AS A STANDARD CONVENTION IN ENDF/B-VI, BUT IS ONLY TO BE RECENT
USED FOR PROCESSED DATA, AS OPPOSED TO THE ORIGINAL EVALUATIONS. RECENT
IN EVALUATIONS WHICH CONTAIN MF=1, MT=451 LRP CAN BE USED TO RECENT
DETERMINE IF THE MATERIAL HAS BEEN PROCESSED. RECENT
RECENT
(2) THE LRU FLAG IN EACH SECTION OF FILE 2 DATA IS CHANGED TO RECENT
LRU=LRU+3. FOR EXAMPLE WHEN READING AN ENDF/B EVALUATION LRU=0 RECENT
(NO RESONANCES), =1 (RESOLVED) OR =2 (UNRESOLVED) INDICATES THAT RECENT
THE DATA IS IN THE ORIGINAL ENDF/B FORM. LRU=3 (NO RESONANCES), RECENT
=4 (RESOLVED) OR =5 (UNRESOLVED) INDICATES THAT THE RESONANCE RECENT
CONTRIBUTION HAS ALREADY BEEN ADDED TO THE FILE 3 DATA. THIS RECENT
SECOND CONVENTION HAS BEEN ADOPTED AS INSURANCE THAT THE RESONANCERECENT
CONTRIBUTION WILL NOT BE ADDED TWICE, EVEN FOR EVALUATIONS WHICH RECENT
DO NOT CONTAIN MF=1, MT=451 (EVALUATIONS WHICH CONTAIN MF=1, RECENT
MT=451 ARE COVERED BY CONVENTION (1), DESCRIBED ABOVE). RECENT
RECENT
UNIFORM TREATMENT OF RESONANCE FORMALISMS RECENT
==================================================================RECENT
NORMALIZATION RECENT
============= RECENT
ALL OF THE RESONANCE FORMALISMS INCLUDE A FACTOR OF, RECENT
RECENT
PI*(FRACTIONAL ABUNDANCE)/(K**2) RECENT
RECENT
THIS FACTOR HAS BEEN REMOVED FROM THE CALCULATION OF EACH TYPE RECENT
OF RESONANCE FORMALISM AND IS APPLIED AS A FINAL NORMALIZATION RECENT
AFTER THE CALCULATION, ONLY ONE PLACE IN THIS PROGRAM. RECENT
RECENT
FOR SIMPLICITY THIS TERM IS NOT INCLUDED IN THE FOLLOWING RECENT
DERIVATIONS - IN ALL CASES THE ACTUAL CROSS SECTION IS A PRODUCT RECENT
OF THE ABOVE FACTOR TIMES THE RESULTS PRESENTED BELOW. RECENT
RECENT
SIMILARITIES RECENT
============ RECENT
FOR THE RESOLVED RESONANCE REGION, EXCEPT FOR SINGLE LEVEL BREIT RECENT
WIGNER, PARAMETERS ALL OF THE FORMALISMS DEFINE THE CROSS SECTIONSRECENT
IN AN EQUIVALENT FORM, RECENT
RECENT
TOTAL = 2*GJ*REAL(1 - U) RECENT
= 2*GJ*(1 - REAL(U)) RECENT
ELASTIC = GJ*(1 - U)**2 RECENT
= GJ*((1 - 2*REAL(U)) + (REAL(U)**2 + IM(U)**2)) RECENT
= 2*GJ*(1 - REAL(U)) - GJ*(1 - (REAL(U)**2 + IM(U)**2)) RECENT
RECENT
SINCE THE FIRST TERM IS THE TOTAL, THE SECOND TERM MUST BE RECENT
ABSORPTION. SO WE FIND, RECENT
RECENT
ABSORPTION = GJ*(1 - (REAL(U)**2 + IM(U)**2)) RECENT

WHERE (X) AND (Y) ARE RELATED TO THE SYMMETRIC AND ANTI-SYMMETRIC RECENT
CONTRIBUTIONS OF THE RESONANCES, RESPECTIVELY. ONLY THE DEFINITIONRECENT
OF (X) AND (Y) WILL BE DIFFERENT FOR EACH RESONANCE FORMALISM. RECENT
BELOW WE WILL SHOW THAT WHAT MIGHT APPEAR TO BE A STRANGE CHOICE RECENT
OF DEFINITION OF THE SIGN OF (X) AND(Y) HAS BEEN SELECTED SO THAT RECENT
FOR BREIT-WIGNER PARAMETERS (X) AND (Y) CORRESPOND EXACTLY TO THE RECENT
SYMMETRIC AND ANTI-SYMMETRIC CONTRIBUTION OF THE RESONANCES. RECENT
RECENT
U = (COS(2*PS) - I*SIN(2*PS))*((1-X) - I*Y) RECENT
= ((1-X)*COS(2*PS) - Y*SIN(2*PS)) RECENT
=-I*((1-X)*SIN(2*PS) + Y*COS(2*PS)) RECENT
RECENT
REAL(U) = ((1-X)*COS(2*PS) - Y*SIN(2*PS)) RECENT
IM(U) =-((1-X)*SIN(2*PS) + Y*COS(2*PS)) RECENT
RECENT
R(U)**2 =((1-X)*COS(2*PS))**2 + (Y*SIN(2*PS))**2 RECENT
-2*(1-X)*Y*COS(2*PS)*SIN(2*PS) RECENT
I(U)**2 =((1-X)*SIN(2*PS))**2 + (Y*COS(2*PS))**2 RECENT
+2*(1-X)*Y*COS(2*PS)*SIN(2*PS) RECENT
RECENT
THE TERMS 2*(1-X)*Y*COS(2*PS)*SIN(2*PS) CANCEL AND UPON USING RECENT
THE IDENTITY COS(2*PS)**2 + SIN(2*PS)**2 = 1, RECENT
RECENT
SUM = (1-X)**2 + (Y)**2 RECENT
RECENT
WE NOW HAVE ALL THE QUANTITIES THAT WE NEED TO DEFINE THE CROSS RECENT
SECTIONS, RECENT
RECENT
ELASTIC RECENT
======= RECENT
ELASTIC =GJ*(1 - 2*REAL(U) + (REAL(U)**2 + IM(U)**2)) RECENT
=GJ*(1 - 2*((1-X)*COS(2*PS)-Y*SIN(2*PS))+(1-X)**2+(Y)**2)RECENT
RECENT
THIS CAN BE WRITTEN AS A SUM OF 2 SQUARES, RECENT
RECENT
ELASTIC =GJ*(COS(2*PS) - (1-X))**2 + (SIN(2*PS) + Y)**2) RECENT
RECENT
=GJ*((COS(2*PS))**2 - 2*(1-X)*COS(2*PS) + (1-X)**2) + RECENT
(SIN(2*PS))**2 + 2*Y*SIN(2*PS) + (Y)**2) RECENT
RECENT
AGAIN USING THE IDENTITY COS(2*PS)**2 + SIN(2*PS)**2 = 1, WE CAN RECENT
SEE THAT THE DEFINITION AS THE SUM OF 2 SQUARES IS IDENTICAL TO RECENT
THE PRECEDING DEFINITION OF THE ELASTIC. RECENT
RECENT
ELASTIC =GJ*(COS(2*PS) - (1-X))**2 + (SIN(2*PS) + Y)**2) RECENT
=GJ*((COS(2*PS)-1) + X)**2 + (SIN(2*PS) + Y)**2) RECENT
RECENT
USING THE IDENTITY (1 - COS(2*PS))) = 2*SIN(PS)**2, WE OBTAIN RECENT
THE FINAL FORM FOR THE ELASTIC, RECENT
RECENT
ELASTIC =GJ*(2*SIN(PS)**2 - X)**2 + (SIN(2*PS) + Y)**2) RECENT
RECENT
ABSORPTION RECENT
========== RECENT
ABSORPTION = GJ*(1 - (REAL(U)**2 + IM(U)**2)) RECENT
= GJ*(1 - ((1-X)**2 + (Y)**2) RECENT
= GJ*(1 - (1 - 2*X + (X)**2 + (Y)**2) RECENT
= GJ*(2*X - (X)**2 + (Y)**2) RECENT
RECENT
SINCE PHYSICALLY THE ABSORPTION CANNOT BE NEGATIVE WE CAN SEE RECENT
THAT (X) MUST BE POSITIVE AND 2*X MUST BE GREATER THAN RECENT
(X)**2 + (Y)**2, FOR ALL OF THE FORMALISMS. RECENT
RECENT
TOTAL RECENT
===== RECENT
IN THIS PROGRAM THE TOTAL CROSS SECTION IS ALWAYS DEFINED TO BE RECENT
THE SUM OF ITS PARTS - SO THE ABOVE DEFINITION IS NEVER EXPLICITLYRECENT
USED. HOWEVER, WE CAN LEARN SOMETHING BY EXAMINING THE DEFINITION,RECENT
RECENT
TOTAL = 2*GJ*REAL(1 - U) RECENT
= 2*GJ*(1 - (((1-X)*COS(2*PS) - Y*SIN(2*PS))) RECENT
= 2*GJ*((1 - COS(2*PS))*(1-X) - (1-X) + Y*SIN(2*PS)) RECENT
= 2*GJ*(2*SIN(PS)**2*(1-X) - (1-X) + Y*SIN(2*PS)) RECENT
RECENT
= 4*GJ*SIN(PS)**2 + RECENT
2*GJ*((X-1) - 2*X*SIN(PS)**2 + Y*SIN(2*PS)) RECENT
RECENT
THE IMPORTANT POINT TO NOTE IS THAT THE DEFINITION OF THE TOTAL RECENT
DOES NOT EXPLICITLY CONTAIN ANY DEPENDENCE ON X**2 AND Y**2 - RECENT
THE LEVEL-LEVEL INTERFERENCE TERMS. RECENT
RECENT
THIS IMPLIES THAT IF A GIVEN SET OF RESONANCE PARAMETERS ARE USED RECENT
WITH THIS DEFINITION THEY WILL PRODUCE EXACTLY THE SAME TOTAL RECENT
CROSS SECTION - WHETHER WE CLAIM THE PARAMETERS HAVE BEEN RECENT
PRODUCED USING A SINGLE OR MULTI-LEVEL FIT. THIS RESULT COULD RECENT
BE VERY MISLEADING, IF THIS RESULT FOR THE TOTAL IS IMPLIED TO RECENT
MEAN THAT ONE INTERPRETATION OR THE OTHER WILL NOT HAVE ANY RECENT
EFFECT ON THE INDIVIDUAL CROSS SECTIONS. RECENT
RECENT
STARTING FROM EXACTLY THE SAME RESONANCE PARAMETERS, RELATIVE TO RECENT
THE RESULTS OBTAINED USING THE SINGLE LEVEL FORMULA, MULTI-LEVEL RECENT
RESULTS WILL TEND TO ALWAYS DECREASE THE ABSORPTION AND INCREASE RECENT
THE ELASTIC. THIS CAN BE IMMEDIATELY SEEN FROM OUR GENERAL RECENT
MULTI-LEVEL DEFINITION OF ABSORPTION, RECENT
RECENT
ABSORPTION =GJ*(2*X - ((X)**2 + (Y)**2)) RECENT
RECENT
THE SINGLE LEVEL ABSORPTION IS, RECENT
RECENT
ABSORPTION =GJ*(2*X) RECENT
RECENT
THE DIFFERENCE BETWEEN THE TWO IS -2*GJ*(X**2 + Y**2), SO THAT RECENT
REGARDLESS OF HOW WE DEFINE (X) AND (Y) THE INCLUSION OF THIS RECENT
TERM WILL ALWAYS DECREASE ABSORPTION. SINCE THE TOTAL CROSS RECENT
SECTION IS THE SAME IN BOTH CASE, THIS MEANS THAT THE ELASTIC RECENT
HAS BEEN INCREASED BY THIS AMOUNT. RECENT
RECENT
AGAIN, THESE RESULTS ARE BASED ON STARTING FROM EXACTLY THE SAME RECENT
PARAMETERS - IN ANY ACTUAL CASE THE PARAMETERS BASED ON A SINGLE RECENT
OR MULTI-LEVEL FIT WILL BE QUITE DIFFERENT - THE POINT THAT WE RECENT
WANT TO STRESS HERE IS THAT YOU SHOULD NEVER USE PARAMETERS RECENT
WHICH HAVE BEEN DEFINED BY A FIT USING ONE FORMALISM - IN THE RECENT
EQUATIONS FOR A DIFFERENT FORMALISM - AND ASSUME THAT THE RESULTS RECENT
WILL BE CONSISTENT - AND NEVER USE THE TOTAL CROSS SECTION TO RECENT
SEE WHETHER OR NOT A SET OF SINGLE LEVEL PARAMETERS CAN BE USED RECENT
WITH A MULTI-LEVEL FORMALISM. RECENT
RECENT
POTENTIAL CROSS SECTION RECENT
======================= RECENT
FAR FROM RESONANCES (X) AND (Y) WILL BE SMALL AND THE ELASTIC RECENT
CROSS SECTION REDUCES TO, RECENT
RECENT
ELASTIC =GJ*(2*SIN(PS)**2)**2 + (SIN(2*PS))**2 RECENT
=GJ*4*(SIN(PS)**4 + SIN(2*PS)**2 RECENT
RECENT
USING THE IDENTITY SIN(2*PS) = 2*SIN(PS)*COS(PS) RECENT
RECENT
=4*GJ*(SIN(PS)**4 + (SIN(PS)*COS(PS))**2) RECENT
=4*GJ*SIN(PS)**2*(SIN(PS)**2 + COS(PS)**2) RECENT
=4*GJ*SIN(PS)**2 RECENT
RECENT
WHICH IS THE POTENTIAL CROSS SECTION. NOTE THAT THIS RESULT IS RECENT
INDEPENDENT OF THE FORMALISM USED, AS IT MUST PHYSICALLY BE, RECENT
AND AS SUCH ALTHOUGH AS YET WE HAVE NOT DEFINED IT, WE CAN RECENT
NOW SEE THAT IN ALL CASES (PS) MUST BE THE PHASE SHIFT AND FOR RECENT
CONSISTENCY IT MUST BE DEFINED USING EXACTLY THE SAME DEFINITION RECENT
IN ALL CASES. RECENT
RECENT
IN ADDITION SINCE PHYSICALLY FOR EACH L VALUE WE EXPECT TO OBTAIN RECENT
A POTENTIAL CROSS SECTION, RECENT
RECENT
4*(2*L+1)*SIN(PS)**2 RECENT
RECENT
OBVIOUSLY FOR CONSISTENCY WE MUST HAVE, RECENT
RECENT
(2*L+1) = (SUM OVER J) GJ RECENT
RECENT
ONLY IN THIS CASE WILL THE RESULTS BE CONSISTENT - THIS POINT WILLRECENT
BE DISCUSSED IN DETAIL BELOW. RECENT
RECENT
WHAT ARE THIS TERMS (X) AND (Y) RECENT
=============================== RECENT
(X) AND (Y) CAN BE EASILY IDENTIFIED BY CONSIDERING THE SINGLE RECENT
AND MULTI-LEVEL BREIT WIGNER FORMALISMS. IN THESE CASES WE WILL RECENT
FIND THAT, RECENT
RECENT
X = GAM(N)*GAM(T)/2/DEN RECENT
Y = GAM(N)*(E-ER)/DEN RECENT
DEN = ((E-ER)**2 + (GAM(T)/2)**2) RECENT
RECENT
EXTREME CARE HAS TO BE USED TO PROPERLY DEFINE (Y) SUCH THAT IT RECENT
IS NEGATIVE FOR E LESS THAN ER AND POSITIVE FOR E GREATER THAN RECENT
ER. I WILL MERELY MENTION THAT THE EQUATIONS FOR ALL FORMALISMS RECENT
IN ENDF-102 DO NOT CONSISTENTLY USE (E - ER) - IN SOME CASES RECENT
THIS IS WRITTEN AS (ER - E), WHICH CAN LEAD TO AN INCORRECT RECENT
SIGN IN THE DEFINITION OF THE (Y) THAT WE REQUIRE. RECENT
RECENT
THE INTERFERENCE TERMS CAN BE WRITTEN IN TERMS OF, RECENT
1) LEVEL-SELF INTERFERENCE = THE CONTRIBUTION OF EACH LEVEL RECENT
INTERFERRING WITH ITSELF RECENT
2) LEVEL-LEVEL INTERFERENCE = THE CONTRIBUTION OF EACH LEVEL RECENT
INTERFERRRING WITH ALL OTHER LEVELS RECENT
RECENT
WE WILL REFER TO THESE TWO AS (L-S) AND (L-L), RECENT
RECENT
X**2 = (GAM(N)*(GAM(T)/2)**2/(DEN)**2 + (L-L) RECENT
= (GAM(N)**2*((GAM(T)/2)**2)/(DEN)**2 + (L-L) RECENT
Y**2 = (GAM(N))**2*((E-ER))**2/(DEN)**2 + (L-L) RECENT
RECENT
X**2+Y**2= GAM(N)**2*DEN/(DEN)**2 = GAM(N)**2/DEN + (L-L) RECENT
RECENT
TO SEE THE EFFECT OF INCLUDING MULTI-LEVEL INTERFERENCE WE CAN RECENT
CONSIDER OUR GENERAL EXPRESSION FOR ABSORPTION, RECENT
RECENT
ABSORPTION =GJ*(2*X - ((X)**2 + (Y)**2)) RECENT
RECENT
AND NOTE THAT FOR BOTH SINGLE AND MULTI-LEVEL BREIT WIGNER THE RECENT
ENDF-102 SAYS TO TREAT ABSORPTION IN A SINGLE LEVEL APPROXIMATION RECENT
I.E., IGNORE LEVEL-LEVEL INTERFERENCE. IF ALL INTERFERENCE IS RECENT
IGNORED THIS IS EQUIVALENT TO COMPLETELY IGNORING X**2 + Y**2 AND RECENT
DEFINING, RECENT
RECENT
ABSORPTION =GJ*2*X RECENT
=2*GJ*GAM(N)*GAM(T)/DEN RECENT
RECENT
WHICH IS INCORRECT - SINCE THIS SEEMS TO INDICATE EVERYTHING IS RECENT
ABSORBED. IN ORDER TO OBTAIN THE CORRECT EXPRESSION WE CANNOT RECENT
COMPLETELY IGNORE INTERFERENCE - WE CAN IGNORE LEVEL-LEVEL RECENT
INTERFERENCE, BUT WE MUST INCLUDE LEVEL-SELF INTERFERENCE, RECENT
RECENT
X**2+Y**2= GAM(N)**2/DEN RECENT
RECENT
ABSORPTION =GJ*(2*X - ((X)**2 + (Y)**2)) RECENT
=GJ*GAM(N)*(GAM(T)-GAM(N))/DEN RECENT
=GJ*GAM(N)*GAM(A)/DEN RECENT
RECENT
SUMMARY RECENT
======= RECENT
AN IMPORTANT POINT TO NOTE IS THE DEFINITION OF (X) AND (Y) RECENT
WHICH IN ALL CASES WILL CORRESPOND TO THE SYMMETRIC AND RECENT
ANTI-SYMMETRIC CONTRIBUTION OF THE RESONANCES. IN PARTICULAR RECENT
DEFINING (U) IN TERMS OF (1-X) INSTEAD OF (X) IS EXTREMELY RECENT
IMPORTANT. NOTE, THAT THE DEFINITION OF THE ELASTIC AND RECENT
ABSORPTION ONLY INVOLVE (X), NOT (1-X). FAR FROM RESONANCES RECENT
(X) CAN BE EXTREMELY SMALL, THEREFORE (1-X) WILL BE VERY CLOSE RECENT
TO (1). IF THE CALCULATION PROCEEDS BY FIRST CALCULATING (1-X) RECENT
AND THEN DEFINING (X) BY SUBTRACTING (1), EXTREME ROUND-OFF RECENT
PROBLEMS CAN RESULT. THESE PROBLEMS CAN BE AVOIDED BY IN ALL RECENT
CASES DEFINING (X) DIRECTLY, WITHOUT ANY DIFFERENCES. RECENT
RECENT
IN EACH FORMALISM THE DEFINITION OF (X) AND (Y) MAY BE DIFFERENT RECENT
BUT ONCE WE HAVE DEFINED (X) AND (Y) WE CAN IMMEDIATELY WRITE RECENT
THE CROSS SECTIONS USING A UNIFORM DEFINITION, RECENT
RECENT
ELASTIC =GJ*(2*SIN(PS)**2 - X)**2 + (SIN(2*PS) + Y)**2) RECENT
RECENT
ABSORPTION =-GJ*(2*X + (X)**2 + (Y)**2) RECENT
RECENT
AND DEFINE THE TOTAL AS THE SUM OF THESE 2 PARTS. RECENT
RECENT
RELATIONSHIP TO SINGLE LEVEL RECENT
============================ RECENT
HOW DO THE SINGLE AND MULTI-LEVEL FORMALISMS COMPARE. TO SEE, RECENT
STARTING FROM OUR GENERAL DEFINITION OF THE ELASTIC IN THE FORM, RECENT
RECENT
ELASTIC =GJ*(2*SIN(PS)**2 + X)**2 + (SIN(2*PS) + Y)**2) RECENT
=GJ*(4*SIN(PS)**4 - 4*X*SIN(PS)**2 + X**2 RECENT
+ SIN(2*PS)**2 + 2*Y*SIN(2*PS) + Y**2) RECENT
RECENT
=4*GJ*SIN(PS)**2 + RECENT
GJ*(X**2 + Y**2 RECENT
-4*X*SIN(PS)**2 RECENT
+2*Y*SIN(2*PS)) RECENT
RECENT
AND OUR SPECIFIC DEFINITIONS OF (X) AND (Y) FOR MULTI-LEVEL BREIT-RECENT
WIGNER PARAMETERS, RECENT
RECENT
X = GAM(N)*GAM(T)/2/DEN RECENT
Y = GAM(N)*(E-ER)/DEN RECENT
DEN = ((E-ER)**2 + (GAM(T)/2)**2) RECENT
RECENT
X**2+Y**2= GAM(N)**2/DEN + (L-L) RECENT
RECENT
WE CAN RECOGNIZE X**2 AND Y**2 AS THE INTERFERENCE - (L-S) + (L-L)RECENT
TERMS IN THE MULTI-LEVEL FORMALISM. IN ORDER TO OBTAIN THE SINGLE RECENT
LEVEL EQUATION WE CAN ASSUME THAT EACH LEVEL DOES NOT INTERFERE RECENT
WITH ANY OTHER LEVEL - THEREFORE THE (L-L) CONTRIBUTION IS ZERO. RECENT
RECENT
ELASTIC =4*GJ*SIN(PS)**2 + RECENT
GJ*GAM(N)*(GAM(N) RECENT
-2*GAM(T)*SIN(PS)**2 RECENT
+2*(E-ER)*SIN(2*PS))/DEN RECENT

TYPOGRAPHICAL ERRORS IN THE SECOND TERM, RECENT

PROGRAM CONVENTIONS RECENT
==================================================================RECENT
MINIMUM INPUT DATA RECENT
------------------ RECENT
FOR EACH MATERIAL TO BE PROCESSED THE MINIMUM INPUT DATA ARE THE RECENT
RESONANCE PARAMETERS IN FILE 2. IF THERE ARE NO FILE 2 PARAMETERS RECENT
IN A GIVEN MATERIAL THE ENTIRE MATERIAL WILL SIMPLY BE COPIED. RECENT
NEITHER THE HOLLERITH SECTION (MF=1, MT=451) NOR THE BACKGROUND RECENT
CROSS SECTION (SECTIONS OF MF=3) NEED BE PRESENT FOR THIS PROGRAM RECENT
TO EXECUTE PROPERLY. HOWEVER, SINCE THE CONVENTIONS USED IN RECENT
INTERPRETING THE RESONANCE PARAMETERS DEPENDS ON ENDF/B VERSION RECENT
USERS ARE STRONGLY RECOMMENDED TO INSURE THAT MF=1, MT=451 IS RECENT
PRESENT IN EACH MATERIAL TO ALLOW THE PROGRAM TO DETERMINE THE RECENT
ENDF/B FORMAT VERSION. RECENT
RECENT
RESONANCE PARAMETERS RECENT
-------------------- RECENT
RESONANCE PARAMETERS MAY BE REPRESENTED USING ANY COMBINATION RECENT
OF THE REPRESENTATIONS ALLOWED IN ENDF/B, RECENT
(1) RESOLVED DATA RECENT
(A) SINGLE LEVEL BREIT-WIGNER RECENT
(B) MULTI-LEVEL BREIT-WIGNER RECENT

THE FOLLOWING RESOLVED DATA FORMALISMS ARE NOT TREATED BY THIS RECENT
VERSION OF THE CODE AND WILL ONLY BE IMPLEMENTED AFTER EVALUATIONSRECENT
USING THESE FORMALISMS ARE AVAILABLE TO THE AUTHOR OF THIS CODE RECENT
FOR TESTING IN ORDER TO INSURE THAT THEY CAN BE HANDLED PROPERLY RECENT
(A) GENERAL R-MATRIX RECENT
RECENT
CALCULATED CROSS SECTIONS RECENT
------------------------- RECENT
THIS PROGRAM WILL USE THE RESONANCE PARAMETERS TO CALCULATE THE RECENT
TOTAL, ELASTIC, CAPTURE AND POSSIBLY FISSION CROSS SECTIONS. THE RECENT
COMPETITIVE WIDTH WILL BE USED IN THESE CALCULATIONS, BUT THE RECENT
COMPETITIVE CROSS SECTION ITSELF WILL NOT BE CALCULATED. THE RECENT
ENDF/B CONVENTION IS THAT ALTHOUGH A COMPETITIVE WIDTH MAY BE RECENT
GIVEN, THE COMPETITIVE CROSS SECTION MUST BE SEPARATELY TABULATED RECENT
AS A SECTION OF FILE 3 DATA. RECENT
RECENT
RESOLVED REGION RECENT
--------------- RECENT
IN THE RESOLVED REGION THE RESOLVED PARAMETERS ARE USED TO RECENT
CALCULATE COLD (0 KELVIN), LINEARLY INTERPOLABLE, ENERGY DEPENDENTRECENT
CROSS SECTIONS. RECENT
RECENT
SCATTERING RADIUS RECENT
----------------- RECENT
FOR SINGLE OR MULTI LEVEL BREIT-WIGNER PARAMETERS THE SCATTERING RECENT
RADIUS MAY BE SPECIFIED IN EITHER ENERGY INDEPENDENT (CONSTANT) RECENT
OR ENERGY DEPENDENT FORM (A TABLE OF ENERGY VS. RADIUS AND AN RECENT
ASSOCIATED INTERPOLATION LAW). IN ALL OTHER CASE ONLY AN ENERGY RECENT
INDEPENDENT SCATTERING RADIUS IS ALLOWED. RECENT
RECENT
FOR ANY ONE MATERIAL (I.E. MAT) IF ENERGY DEPENDENT SCATTERING RECENT
RADII ARE GIVEN THE TOTAL NUMBER OF INTERPOLATION REGIONS AND RECENT
TABULATED VALUES FOR THE ENTIRE MATERIAL CANNOT EXCEED, RECENT
200 - INTERPOLATION REGIONS RECENT
500 - TABULATED VALUES RECENT
IF THESE LIMITS ARE EXCEEDED THE PROGRAM WILL PRINT AN ERROR RECENT
MESSAGE AND TERMINATE. RECENT
RECENT
IF YOU REQUIRE A LARGER NUMBER OF INTERPOLATION REGION AND/OR RECENT
TABULATED VALUES, RECENT
(1) INTERPOLATION REGIONS - INCREASE THE DIMENSION OF NBTRHO AND RECENT
INTRHO IN COMMON/TABRHO/ THROUGHOUT THE PROGRAM AND CHANGE MAXSEC RECENT
IN SUBROUTINE RDAP (MAXSEC = MAXIMUM NUMBER OF INTERPOLATION RECENT
REGIONS). RECENT
(2) TABULATED VALUES - INCREASE THE DIMENSION OF ERHOTB, RHOTAB RECENT
AND APTAB IN COMMON/TABRHO/ THROUGHOUT THE PROGRAM AND CHANGE RECENT
MAXRHO IN SUBROUTINE RDAP (MAXRHO = MAXIMUM NUMBER OF TABULATED RECENT
VALUES). RECENT
RECENT
RESOLVED REICH-MOORE AND MULTI-LEVEL BREIT-WIGNER PARAMETERS RECENT
------------------------------------------------------------ RECENT
CROSS SECTIONS FOR REICH-MOORE PARAMETERS ARE CALCULATED ACCORDINGRECENT
TO THE EQUATION (1) - (8) OF SECTION D.1.3 OF ENDF-102. IN ORDER RECENT
TO CALCULATE CROSS SECTIONS FROM MULTI-LEVEL PARAMETERS IN A RECENT
REASONABLE AMOUNT OF TIME THIS PROGRAM EXPRESSES THE CROSS SECTIONRECENT
IN TERMS OF A SINGLE SUM OVER RESONANCES (SEE, ENDF-102, SECTION RECENT
D.1.2, EQUATIONS 6-7), RATHER THAN AS A DOUBLE SUM (SEE, ENDF-102 RECENT
SECTION D.1.2, EQUATION 1-2). IN ORDER FOR THE ENDF-102 EQUATIONS RECENT
TO BE CORRECT THE PARAMETERS MUST MEET THE FOLLOWING CONDITIONS, RECENT
RECENT
(1) FOR EACH L STATE ALL PHYSICALLY POSSIBLE J SEQUENCES MUST BE RECENT
PRESENT. ONLY IN THIS CASE WILL THE CONTRIBUTIONS OF THE RECENT
INDIVIDUAL J SEQUENCES ADD UP TO PRODUCE THE CORRECT POTENTIALRECENT
SCATTERING CONTRIBUTION FOR THE L STATE (SEE, ENDF-102, RECENT
SECTION D.1.2, EQUATIONS 6-7). IF ANY J SEQUENCE IS MISSING RECENT
THE PROGRAM WILL PRINT A WARNING AND ADD THE J SEQUENCE WITH RECENT
NO RESONANCE PARAMETERS IN ORDER TO ALLOW THE POTENTIAL RECENT
SCATTERING TO BE CALCULATED CORRECTLY (THIS IS EQUIVALENT TO RECENT
ASSUMING THAT THE EVALUATOR REALIZES THAT ALL J SEQUENCES MUSTRECENT
BE AND ARE PRESENT AND THAT THE EVALUATION STATES THAT THERE RECENT
ARE NO RESONANCES WITH CERTAIN PHYSICALLY POSSIBLE J VALUES...RECENT
IN THIS CASE POTENTIAL CONTRIBUTION MUST STILL BE CONSIDERED).RECENT
RECENT
EXAMPLE RECENT
======= RECENT
AN EXAMPLE OF WHERE THIS OCCURS AND IS IMPORTANT TO CONSIDER RECENT
IS U-238 IN ENDF/B-4 AND 5 LIBRARIES WHERE FOR L=1 THERE IS RECENT
ONLY A J=1/2 SEQUENCE. NOT INCLUDING THE J=3/2 SEQUENCE LEADS RECENT
TO UNDERESTIMATING THE POTENTIAL SCATTERING AND PRODUCES RECENT
MINIMA IN THE ELASTIC CROSS SECTION WHICH ARE AN ORDER OF RECENT
MAGNITUDE LOWER THAN THE CROSS SECTIONS OBTAINED BE INCLUDING RECENT
THE J=3/2 SEQUENCE. RECENT
RECENT
(2) FOR A GIVEN TARGET SPIN AND L VALUE THERE MAY BE 2 POSSIBLE RECENT
MEANS OF OBTAINING THE SAME J VALUE. WHEN THIS OCCURS IN RECENT
ORDER TO CALCULATE THE CORRECT POTENTIAL SCATTERING CROSS RECENT
SECTION IT IS IMPORTANT TO INCLUDE THE EFFECT OF BOTH RECENT
POSSIBLE J SEQUENCES, EVEN THOUGH FROM THE ENDF/B DATA IT IS RECENT
NOT POSSIBLE TO DETERMINE WHICH OF THE 2 POSSIBLE SEQUENCES RECENT
ANY GIVEN RESONANCE BELONGS TO. IN THIS CASE THIS PROGRAM RECENT
TREAT ALL RESONANCES WITH THE SAME J VALUE AS BELONGING TO RECENT
THE SAME J SEQUENCE (TO ALLOW INTERFERENCE) AND WILL ADD AN RECENT
ADDITIONAL J SEQUENCE WITH NO RESONANCES IN ORDER TO ALLOW RECENT
THE POTENTIAL CROSS SECTION TO BE CALCULATED CORRECTLY. WHEN RECENT
THIS OCCURS A WARNING MESSAGE IS PRINTED, BUT BASED ON THE RECENT
ENDF/B DATA THERE IS NOTHING WRONG WITH THE DATA AND THERE IS RECENT
NOTHING THAT THE USER CAN DO TO CORRECT OR IN ANY WAY MODIFY RECENT
THE DATA TO ELIMINATE THE PROBLEM. RECENT
RECENT
EXAMPLE RECENT
======= RECENT
FOR A TARGET SPIN =1 AND L=1 THE 2 RANGES OF PHYSICALLY RECENT
POSSIBLE J ARE 1/2, 3/2, 5/2 AND 1/2, 3/2. BY CHECKING THE RECENT
ENDF/B DATA IT IS POSSIBLE TO INSURE THAT THE 3 POSSIBLE RECENT
J VALUES (1/2, 3/2, 5/2) ARE PRESENT AND TO INCLUDE ALL 3 RECENT
J SEQUENCES IN THE CALCULATIONS. HOWEVER, UNLESS ALL 5 RECENT
POSSIBLE J SEQUENCES ARE INCLUDED THE STATISTICAL WEIGHTS RECENT
OF THE J SEQUENCES WILL NOT SUM UP TO 2*L+1 AND THE RECENT
POTENTIAL CROSS SECTION WILL BE UNDERESTIMATED. IN THIS RECENT
EXAMPLE THE SUM OF THE 3 J SEQUENCES 1/2, 3/2, 5/2 IS 2, RECENT
RATHER THAN 3 AS IT SHOULD BE FOR L=1, AND THE CONTRIBUTION RECENT
OF THE L=1 RESONANCES TO THE POTENTIAL SCATTERING CROSS RECENT
SECTION WILL ONLY BE 2/3 OF WHAT IT SHOULD BE, UNLESS THE RECENT
OTHER 2 J SEQUENCES (WITH DUPLICATE J VALUES) ARE INCLUDED RECENT
IN THE CALCULATION. RECENT
RECENT
(3) EACH RESONANCE MUST HAVE AN ASSIGNED, PHYSICALLY POSSIBLE RECENT
J VALUE. PHYSICALLY IMPOSSIBLE OR AVERAGE J VALUES CANNOT BE RECENT
UNIQUELY INTERPRETED USING THE EQUATIONS IN ENDF-102 AND RECENT
THEIR USE WILL USUALLY RESULT IN PHYSICALLY UNRELIABLE CROSS RECENT
SECTIONS. THIS PROGRAM WILL CHECK ALL J VALUES AND IF ANY ARE RECENT
ARE FOUND TO BE PHYSICALLY IMPOSSIBLE (BASED ON TARGET SPIN RECENT
AND L VALUE) AN ERROR MESSAGE WILL BE PRINTED TO INDICATE THATRECENT
THE RECONSTRUCTED CROSS SECTIONS WILL BE UNRELIABLE AND THE RECENT
PROGRAM WILL CONTINUE. IN AN ATTEMPT TO CALCULATE THE CORRECT RECENT
POTENTIAL SCATTERING CROSS SECTION THIS PROGRAM WILL SUBTRACT RECENT
THE POTENTIAL SCATTERING CONTRIBUTION DUE TO ALL FICTICIOUS J RECENT
SEQUENCES AND ADD THE CONTRIBUTION OF ALL PHYSICALLY POSSIBLE RECENT
J SEQUENCES (AS DESCRIBED ABOVE). RECENT
RECENT
WARNING (LET THE USER BEWARE) RECENT
============================= RECENT
(A) IT CANNOT BE STRESSED ENOUGH THAT CROSS SECTIONS OBTAINED RECENT
USING PHYSICALLY IMPOSSIBLE J VALUES FOR REICH-MOORE AND RECENT
MULTI-LEVEL BREIT-WIGNER RESONANCE PARAMETERS WILL RESULT RECENT
IN UNRELIABLE CROSS SECTIONS. THE DECISION TO HAVE THIS RECENT
PROGRAM CONTINUE TO PROCESS WHEN THIS CONDITION IS FOUND RECENT
IS BASED ON AN ATTEMPT TO ALLOW THE USER TO AT LEAST HAVE RECENT
SOME RESULTS (HOWEVER BAD THEY MAY BE) IF THERE IS NO RECENT
OTHER EVALUATED DATA AVAILABLE. RECENT
(B) EVEN THOUGH THE REICH-MOORE AND MULTI-LEVEL EQUATIONS ARE RECENT
DEFINED AS ABSOLUTE OR SQUARED CONTRIBUTIONS WHICH MUST RECENT
ALL BE PHYSICALLY POSSIBLE, ATTEMPTING TO CORRECT THE RECENT
POTENTIAL CROSS SECTION (AS DESCRIBED ABOVE) CAN LEAD TO RECENT
NEGATIVE ELASTIC CROSS SECTIONS. THIS IS BECAUSE BASED ON RECENT
THE INFORMATION AVAILABLE IN THE EVALUATION IT IS NOT RECENT
NOT POSSIBLE TO CORRECTLY ACCOUNT FOR THE INTERFERENCE RECENT
BETWEEN THE RESONANCE AND POTENTIAL CONTRIBUTIONS FOR EACHRECENT
J SEQUENCE. RECENT
RECENT
UNRESOLVED RESONANCE REGION RECENT
--------------------------- RECENT
IN THE UNRESOLVED RESONANCE REGION THE UNRESOLVED PARAMETERS RECENT
ARE USED TO CALCULATE INFINITELY DILUTE AVERAGE CROSS SECTIONS. RECENT
NOTE, IT IS IMPORTANT TO UNDERSTAND THAT FROM THE DEFINITION OF RECENT
THE UNRESOLVED PARAMETERS IT IS NOT POSSIBLE TO UNIQUELY CALCULATERECENT
ENERGY DEPENDENT CROSS SECTIONS. ONLY AVERAGES OR DISTRIBUTIONS RECENT
MAY BE CALCULATED. RECENT
RECENT
UNRESOLVED INTERPOLATION RECENT
------------------------ RECENT
IN THE UNRESOLVED RESONANCE REGION CROSS SECTIONS AT EACH ENERGY RECENT
ARE CALCULATED BY INTERPOLATING PARAMETERS. THIS IS THE CONVENTIONRECENT
USED IN ENDF/B-4 AND EARLIER VERSIONS OF ENDF/B. THE ENDF/B-5 RECENT
CONVENTION OF INTERPOLATING CROSS SECTIONS, NOT PARAMETERS, HAS RECENT
BEEN ABANDONED AS IMPRACTICAL SINCE IT CAN LEAD TO THE SITUATION RECENT
WHERE EXACTLY THE SAME PHYSICAL DATA CAN LEAD TO DIFFERENT RESULTSRECENT
DEPENDING ON WHICH OF THE THREE ENDF/B UNRESOLVED PARAMTER FORMATSRECENT
IS USED. FOR EXAMPLE, GIVEN A SET OF ENERGY INDEPENDENT UNRESOLVEDRECENT
PARAMETERS IT IS POSSIBLE TO CODE THESE PARAMETERS IN EACH OF THE RECENT
THREE ENDF/B UNRESOLVED PARAMETER FORMATS. SINCE PHYSICALLY WE RECENT
ONLY HAVE ONE SET OF PARAMETERS WE WOULD EXPECT THE RESULTS TO BE RECENT
INDEPENDENT OF HOW THEY ARE REPRESENTED IN ENDF/B. UNFORTUNATELY RECENT
USING THE ENDF/B-5 CONVENTION TO INTERPOLATE CROSS SECTIONS CAN RECENT
LEAD TO THREE COMPLETELY DIFFERENT RESULTS. IN CONTRAST USING THE RECENT
ENDF/B-4 AND EARLIER CONVENTION OF INTERPOLATING PARAMETERS LEADS RECENT
TO COMPLETELY CONSISTENT RESULTS. RECENT
RECENT
INTERNAL REPRESENTATION OF UNRESOLVED PARAMETERS RECENT
------------------------------------------------ RECENT
ANY OF THE THREE POSSIBLE REPRESENTATIONS OF UNRESOLVED PARAMETERSRECENT
CAN BE UNIQUELY REPRESENTED IN THE ALL PARAMETERS ENERGY DEPENDENTRECENT
REPRESENTATIONS WITH THE APPROPRIATE (ENDF/B VERSION DEPENDENT) RECENT
INTERPOLATION LAW. THIS IS DONE BY THE PROGRAM WHILE READING THE RECENT
UNRESOLVED PARAMETERS AND ALL SUBSEQUENT CALCULATIONS NEED ONLY RECENT
CONSIDER THE ALL PARAMETERS ENERGY DEPENDENT REPRESENTATION. RECENT
RECENT
RESONANCE RECONSTRUCTION STARTING ENERGY GRID RECENT
--------------------------------------------- RECENT
AS IN ANY ITERATIVE METHOD THE WAY TO SPEED CONVERGENCE IS TO TRY RECENT
TO START CLOSE TO THE ANSWER. THIS PROGRAM ATTEMPTS TO DO THIS BY RECENT
STARTING FROM AN ENERGY GRID WHICH IS A GOOD APPROXIMATION TO A RECENT
SIMPLE BREIT-WIGNER LINE SHAPE, RECENT
RECENT
SIGMA(X)=1.0/(1.0+X*X) RECENT
RECENT
WHERE X IS THE DISTANCE FROM THE PEAK IN HALF-WIDTHS RECENT
RECENT
SUBROUTINE SUBINT HAS A BUILT-IN TABLE OF NODES WHICH ARE THE RECENT
HALF-WIDTH MULTIPLES TO APPROXIMATE THE SIMPLE BREIT-LINE SHAPE RECENT
TO WITHIN 1 PER-CENT OVER THE ENTIRE INTERVAL 0 TO 500 HALF-WIDTHSRECENT
RECENT
BETWEEN ANY TWO RESOLVED RESONANCES THE STARTING GRID IS BASED ON RECENT
THE HALF-WIDTHS OF THE TWO RESONANCES. FROM THE LOWER ENERGY RECENT
RESONANCE UP TO THE MID-POINT BETWEEN THE RESONANCES (MID-POINT RECENT
IS DEFINED HERE AS AN EQUAL NUMBER OF HALF-WIDTHS FROM EACH RECENT
RESONANCE) THE HALF-WIDTH OF THE LOWER ENERGY RESONANCE IS USED. RECENT
FROM THE MID-POINT UP TO THE HIGHER ENERGY RESONANCE THE HALF- RECENT
WIDTH OF THE UPPER ENERGY RESONANCE IS USED. RECENT
RECENT
WITH THIS ALOGORITHM CLOSELY SPACED RESONANCES WILL HAVE ONLY RECENT
A FEW STARTING NODES PER RESONANCE (E.G. U-235). WIDELY SPACED RECENT
RESONANCES WILL HAVE MORE NODES PER RESONANCE (E.G. U-238). FOR RECENT
A MIX OF S, P, D ETC. RESONANCES THIS ALOGORITHM GUARANTEES AN RECENT
ADEQUTE DESCRIPTION OF THE PROFILE OF EVEN EXTREMELY NARROW RECENT
RESONANCES (WHICH MAY IMMEDIATELY CONVERGENCE TO THE ACCURACY RECENT
REQUESTED, THUS MINIMIZING ITERATION). RECENT
RECENT
BACKGROUND CROSS SECTIONS RECENT
------------------------- RECENT
THE PROGRAM WILL SEARCH FOR BACKGROUND CROSS SECTIONS FOR TOTAL RECENT
(MT=1), ELASTIC (MT=2), FISSION (MT=18), FIRST CHANCE FISSION RECENT
(MT=19) AND CAPTURE (MT=102). RECENT
RECENT
(1) THE BACKGROUND CROSS SECTIONS (FILE 3) CAN BE PRESENT OR NOT RECENT
PRESENT FOR EACH REACTION. RECENT
(2) IF FOR A GIVEN REACTION THE BACKGROUND CROSS SECTION IS RECENT
PRESENT, IT WILL BE ADDED TO THE RESONANCE CONTRIBUTION AND RECENT
THE RESULT WILL BE OUTPUT. RECENT
(3) IF FOR A GIVEN REACTION THE BACKGROUND IS NOT PRESENT THE RECENT
PROGRAM WILL, RECENT
(A) IF THE INPUT TO THE PROGRAM SPECIFIES NO OUTPUT FOR RECENT
REACTIONS WITH NO BACKGROUND THERE WILL BE NO OUTPUT. RECENT
(B) IF THE INPUT TO THE PROGRAM SPECIFIES OUTPUT FOR REACTIONSRECENT
WITH NO BACKGROUND, RECENT
(I) THE RESONANCE CONTRIBUTION TO TOTAL, ELASTIC OR RECENT
CAPTURE WILL BE OUTPUT. RECENT
(II) IF ALL FISSION RESONANCE PARAMETERS ARE ZERO THE RECENT
FISSION CROSS SECTION (MT=18) WILL NOT BE OUTPUT. RECENT
OTHERWISE THE RESONANCE CONTRIBUTION OF THE FISSION RECENT
(MT=18) WILL BE OUTPUT. RECENT
(III) THERE WILL BE NO OUTPUT FOR FIRST CHANCE FISSION RECENT
(MT=19). RECENT
RECENT
COMBINING RESONANCES AND BACKGROUND CROSS SECTIONS RECENT
-------------------------------------------------- RECENT
IN ORDER TO BE COMBINED WITH THE RESONANCE CONTRIBUTION THE RECENT
BACKGROUND CROSS SECTIONS MUST BE GIVEN AT 0 KELVIN TEMPERATURE RECENT
AND MUST BE LINEARLY INTERPOLABLE. IF THESE CONDITIONS ARE MET RECENT
THE RESONANCE AND BACKGROUND CONTRIBUTIONS WILL BE ADDED TOGETHER RECENT
AND OUTPUT. IF THESE CONDITIONS ARE NOT MET THE BACKGROUND CROSS RECENT
SECTION WILL BE IGNORED AND ONLY THE RESONANCE CONTRIBUTION WILL RECENT
BE OUTPUT. IF THE BACKGROUND HAS NOT BEEN ADDED TO THE RESONANCE RECENT
CONTRIBUTION AFTER THIS PROGRAM FINISHES THE USER CAN MAKE THE RECENT
RESONANCE AND BACKGROUND CONTRIBUTIONS COMPATIBLE BY, RECENT

(1) IF THE BACKGROUND IS NOT LINEARLY INTERPOABLE, LINEARIZE THE RECENT
BACKGROUND (E.G., USE PROGRAM LINEAR). RECENT
(2) IF THE BACKGROUND IS NOT GIVEN AT 0 KELVIN, DOPPLER BROADEN RECENT
THE RESONANCE (NOT BACKGROUND) CONTRIBUTION TO THE SAME RECENT
TEMPERATURE AS THE BACKGROUND (E.G., USE PROGRAM SIGMA1). RECENT
RECENT
ONCE THE RESONANCE AND BACKGROUND CONTRIBUTIONS HAVE BEEN MADE RECENT
COMPATIBLE THEY CAN BE ADDED TOGETHER (E.G., USE PROGRAM MIXER). RECENT
RECENT
THE RECONSTRUCTION OF THE RESONANCE CONTRIBUTION TO THE CROSS RECENT
SECTION CAN BE QUITE EXPENSIVE (IN TERMS OF COMPUTER TIME). SINCE RECENT
THE RECONSTRUCTION IS PERFORMED BEFORE THE BACKGROUND CROSS RECENT
SECTIONS ARE READ, THE ABOVE CONVENTIONS HAVE BEEN ADOPTED IN RECENT
ORDER TO AVOID LOSE OF COMPUTER TIME INVOLVED IN RECONSTRUCTING RECENT
THE RESONANCE CONTRIBUTION. RECENT
RECENT
COMMON ENERGY GRID RECENT
------------------ RECENT
THIS PROGRAM WILL RECONSTRUCT THE RESONANCE CONTRIBUTION TO THE RECENT
TOTAL, ELASTIC, FISSION AND CAPTURE CROSS SECTIONS ALL ON THE RECENT
SAME ENERGY GRID. EACH REACTION WILL THEN BE COMBINED WITH ITS RECENT
BACKGROUND CROSS SECTION (IF ANY) AND OUTPUT WITHOUT ANY FURTHER RECENT
THINNING. IF THERE ARE NO BACKGROUND CROSS SECTIONS, OR IF THE RECENT
BACKGROUND CROSS SECTION FOR ALL FOUR REACTIONS ARE GIVEN ON A RECENT
COMMON ENERGY GRID, THE OUTPUT FROM THIS PROGRAM WILL BE ON A RECENT
COMMON ENERGY GRID FOR ALL FOUR REACTIONS. RECENT
RECENT
THERMAL ENERGY RECENT
-------------- RECENT
IF THE RESONANCE REGION SPANS THERMAL ENERGY (0.0253 EV) THIS RECENT
POINT IS ALWAYS INCLUDED IN THE COMMON ENERGY GRID USED FOR ALL RECENT
REACTIONS AND WILL ALWAYS APPEAR IN THE OUTPUT DATA. RECENT
RECENT
SECTION SIZE RECENT
------------ RECENT
SINCE THIS PROGRAM USES A LOGICAL PAGING SYSTEM THERE IS NO LIMIT RECENT
TO THE NUMBER OF POINTS IN ANY SECTION, E.G., THE TOTAL CROSS RECENT
SECTION MAY BE REPRESENTED BY 200,000 DATA POINTS. RECENT
RECENT
SELECTION OF DATA RECENT
----------------- RECENT
THE PROGRAM SELECTS MATERIALS TO BE PROCESSED BASED EITHER ON RECENT
MAT (ENDF/B MAT NO.) OR ZA. THE PROGRAM ALLOWS UP TO 100 MAT OR RECENT
ZA RANGES TO BE SPECIFIED. THE PROGRAM WILL ASSUME THAT THE RECENT
ENDF/B TAPE IS IN EITHER MAT OR ZA ORDER, WHICHEVER CRITERIA IS RECENT
USED TO SELECT MATERIALS, AND WILL TERMINATE WHEN A MAT OR ZA RECENT
IS FOUND THAT IS ABOVE THE RANGE OF ALL REQUESTS. RECENT
RECENT
ALLOWABLE ERROR RECENT
--------------- RECENT
THE RECONSTRUCTION OF LINEARLY INTERPOLABLE CROSS SECTIONS FROM RECENT
RESONANCE PARAMETERS CANNOT BE PERFORMED EXACTLY. HOWEVER IT CAN RECENT
BE PERFORMED TO VIRTUALLY ANY REQUIRED ACCURACY AND MOST RECENT
IMPORTANTLY CAN BE PERFORMED TO A TOLERANCE THAT IS SMALL COMPAREDRECENT
TO THE UNCERTAINTY IN THE CROSS SECTIONS THEMSELVES. AS SUCH THE RECENT
CONVERSION OF CROSS SECTIONS TO LINEARLY INTERPOLABLE FORM CAN BE RECENT
PERFORMED WITH ESSENTIALLY NO LOSS OF INFORMATION. RECENT
RECENT
THE ALLOWABLE ERROR MAY BE ENERGY INDEPENDENT (CONSTANT) OR ENERGYRECENT
DEPENDENT. THE ALLOWABLE ERROR IS DESCRIBED BY A TABULATED RECENT
FUNCTION OF UP TO 20 (ENERGY,ERROR) PAIRS AND LINEAR INTERPOLATIONRECENT
BETWEEN TABULATED POINTS. IF ONLY ONE TABULATED POINT IS GIVEN THERECENT
ERROR WILL BE CONSIDERED CONSTANT OVER THE ENTIRE ENERGY RANGE. RECENT
WITH THIS ENERGY DEPENDENT ERROR ONE MAY OPTIMIZE THE OUTPUT FOR RECENT
ANY GIVEN APPLICATION BY USING A SMALL ERROR IN THE ENERGY RANGE RECENT
OF INTEREST AND A LESS STRINGENT ERROR IN OTHER ENERGY RANGES, RECENT
E.G., 0.1 PER-CENT FROM 0 UP TO THE LOW EV RANGE AND A LESS RECENT
STRINGENT TOLERANCE AT HIGHER ENERGIES. RECENT
RECENT
DEFAULT ALLOWABLE ERROR RECENT
----------------------- RECENT
IN ORDER TO INSURE CONVERENCE OF THE RESONANCE RECONSTRUCTION THE RECENT
ALLOWABLE ERROR MUST BE POSITIVE. IF THE USER INPUTS AN ERROR FOR RECENT
RESONANCE RECONSTRUCTION THAT IS NOT POSITIVE IT WILL BE SET TO RECENT
THE DEFAULT VALUE (CURRENTLY 0.1 PER-CENT) AND INDICATED AS SUCH RECENT
IN THE OUTPUT LISTING. RECENT
RECENT
INTERVAL HALVING ALGORITHM RECENT
------------------------- RECENT
THIS PROGRAM WILL START BY CALCULATING THE CROSS SECTIONS AT THE RECENT
ENERGIES CORRESPONDING TO THE PEAK OF EACH RESONANCE, AS WELL AS RECENT
A FIXED NUMBER OF HALF-WIDTHS ON EACH SIDE OF EACH RESONANCE. RECENT
STARTING FROM THIS BASIC GRID OF POINTS THE PROGRAM WILL CONTINUE RECENT
TO HALF EACH INTERVAL UNTIL THE CROSS SECTIONS FOR ALL REACTIONS RECENT
AT THE CENTER OF THE INTERVAL CAN BE DEFINED BY LINEAR RECENT
INTERPOLATION FROM THE ENDS OF THE INTERVAL TO WITHIN THE USER RECENT
SPECIFIED ACCURACY CRITERIA. RECENT
RECENT
DISTANT RESONANCE TREATMENT RECENT
--------------------------- RECENT
THE OPTION TO TREAT DISTANT RESONANCES, WHICH WAS AVAILABLE IN RECENT
EARLIER VERSIONS OF THIS PROGRAM, IS NO LONGER AVAILABLE, BECAUSE RECENT
IT WAS FOUND TO PRODUCE UNRELIABLE RESULTS. IN THIS VERSION OF RECENT
THE PROGRAM ALL RESONANCES ARE TREATED EXACTLY. RECENT

PROGRAM OPERATION RECENT
==================================================================RECENT
EDIT MODE RECENT
--------- RECENT
IT IS SUGGESTED THAT BEFORE RUNNING THIS PROGRAM TO RECONSTRUCT RECENT
CROSS SECTIONS FROM RESONANCE PARAMETERS (WHICH CAN BE QUITE RECENT
EXPENSIVE) THE USER FIRST RUN THE PROGRAM IN THE EDIT MODE (SEE, RECENT
DESCRIPTION OF INPUT PARAMETERS BELOW). IN THE EDIT MODE THE RECENT
PROGRAM WILL READ, LIST AND EXTENSIVELY CHECK THE CONSISTENCY OF RECENT
ALL RESONANCE PARAMETERS AND ENDF/B DEFINED RESONANCE FLAGS. THIS RECENT
IS A VERY INEXPENSIVE MEANS OF CHECKING ALL DATA BEFORE INVESTING RECENT
A LARGE AMOUNT OF MONEY IN RECONSTRUCTING CROSS SECTIONS. ANY AND RECENT
ALL DIGNOSTICS RECEIVED FROM THE EDIT WILL SUGGEST HOW TO CORRECT RECENT
THE EVALUATED DATA TO MAKE IT CONSISTENT BEFORE RECONSTRUCTING RECENT
CROSS SECTIONS. IN ORDER TO OBTAIN MEANINGFUL RESULTS FROM THE RECENT
RECONSTRUCTION ALL SUGGESTED CHANGES TO THE EVALUATION SHOULD BE RECENT
PERFORMED BEFORE TRYING RECONSTRUCTION (OTHERWISE THE RESULT OF RECENT
RECONSTRUCTION WILL NOT BE RELIABLE). RECENT

==================================================================RECENT
MODERN EVALUATIONS MAY BE EXTREMELY LARGE AND IT MAY NOT BE RECENT
POSSIBLE TO PROCESS AN ENTIRE EVALUATION (I.E., ADD THE RESONANCE RECENT
CONTRIBUTION) DURING A SINGLE COMPUTER RUN. RECENT
RECENT
ALSO IN THE CASE WHERE YOU ARE ONLY INTERESTED IN THE CROSS RECENT

CROSS SECTIONS ARE NEAR THERMAL ENERGY, 0.0253 EV. RECENT
RECENT
IN ORDER TO ALLOW AN EVALUATION TO BE PROCESSED USING A NUMBER OF RECENT
SHORTER COMPUTER RUNS AN OPTION HAS BEEN ADDED TO THIS PROGRAM TO RECENT
ALLOW THE USER TO SPECIFY THE ENERGY RANGE TO BE PROCESSED. RECENT
RECENT
USING THIS OPTION YOU MAY START AT THE LOWEST ENERGY (ZERO UP TO RECENT
SOME ENERGY) AND USE THE RESULTS OF THIS RUN AS INPUT TO THE RECENT
NEXT RUN, WHERE YOU CAN SPECIFY THE NEXT ENERGY RANGE. THIS RECENT
CYCLE CAN BE REPEATED UNTIL YOU HAVE PROCESSED THE ENTIRE RECENT
EVALUATION. RECENT
RECENT
WARNING - THIS OPTION SHOULD BE USED WITH EXTREME CARE - THIS RECENT
OPTION HAS BEEN RELUCTANTLY ADDED - RELUCTANTLY BECAUSE IT CAN RECENT
BE EXTREMELY DANGEROUS TO USE THIS OPTION UNLESS YOU CAREFULLY RECENT
CHECKED WHAT YOU ARE DOING. RECENT
RECENT
THE OPTION SHOULD ONLY BE USED AS FOLLOWS, RECENT
1) YOU MUST PROCESS USING ENERGY RANGES STARTING AT LOW ENERGY RECENT
AND WORKING YOUR WAY TOWARD HIGH ENERGY, E.G., RECENT
0.0 TO 3.0+3 RECENT
3.0+3 TO 10.0+3 RECENT
10.0+3 TO 80.0+3, ETC. RECENT
2) FOR THE LAST ENERGY RANGE THE LOWER ENERGY LIMIT MUST BE RECENT
NON-ZERO (WHERE TO START) AND THE UPPER ENERGY LIMIT MUST RECENT
BE ZERO (NO LIMIT) RECENT
80.0+3 TO 0.0 RECENT
RECENT
IF YOU ARE ONLY INTERESTED IN THE CROSS SECTION OVER A NARROW RECENT
ENERGY INTERVAL AND DO NOT INTENT TO MAKE ANY OTHER USE OF THE RECENT
RESULTS, YOU CAN IGNORE THESE WARNINGS AND MERELY SPECIFY ANY RECENT
ENERGY INTERVAL OVER WHICH YOU WISH CALCULATIONS TO BE RECENT
PERFORMED. RECENT
RECENT
NORMALLY WHEN THIS PROGRAM PROCESSES AN EVALUATION IT WILL SET RECENT
FLAGS IN THE EVALUATION TO PREVENT THE SAME RESONANCE RECENT
CONTRIBUTION FROM BEING ADDED TO THE CROSS SECTION MORE THAN RECENT
ONCE, SHOULD YOU USE THE OUTPUT FROM THIS PROGRAM AS INPUT TO RECENT
THE PROGRAM. RECENT
RECENT
WHEN PROCESSING ONLY PORTIONS OF THE RESONANCE REGION THIS RECENT
PROGRAM CANNOT SET THESE FLAGS TO PROTECT AGAINST ADDING THE RECENT
RESONANCE CONTRIBUTION MORE THAN ONCE - WHICH MAKES USE OF RECENT
THIS OPTION EXTREMELY DANGEROUS. RECENT
RECENT
ONLY YOU CAN CHECK TO MAKE SURE THAT YOU HAVE CORRECTLY RECENT
