For several years, Paul and Schinner carried out statistical comparisons between experimental data of electronic stopping power and various tables and programs. See for example: H. Paul and A. Schinner (2001), "An empirical approach to the stopping power of solids and gases for ions from 3Li to 18Ar", Nucl. Instr. Meth. Phys. Res. B 179, 299.
The purpose is to determine the reliability of the tables and programs, and also to find unreliable experimental data sets (see sect. E below).
For a certain range of Z1, for a certain range of target atomic numbers Z2, and for every data point in a certain range of specific energy E/A1 (where Z1 is the projectile’s atomic number, E its energy and A1 its mass number), we calculate the normalized difference . Here, is the mass stopping power, ρ is the density, is the linear stopping power, and x is the path length. In every range of specific energy, we then determine the mean normalized difference and its standard deviation , using our program „Judge“ [1]. Here, signifies an unweighted average, Sexp is an experimental stopping power value taken from our collection, and Stable the corresponding value from a particular stopping power table or program. A small |Δ| usually signifies good agreement between table and data, and the standard deviation σ is related to the accuracy of the experimental data. If |Δ| is small, as we frequently find, σ may be taken as a measure of the accuracy of the table, as determined from experiment. The number of data points is also given in the tables, as an indication of the size of the data base.
The averages are unweighted, except for the data that were excluded from the analysis, i.e., given weight zero, since they were found in conflict with respect to other data of the same Z1-Z2-combination (where Z2 is the atomic number of the target element). Solids and gases (i.e., substances that solid or gaseous, resp., at normal temperature and pressure) are treated separately.
The following statistical analyses are taken from reference [2]. The data are compared to tables by Andersen and Ziegler [3]; Ziegler [4]; Janni [5]; Ziegler, Biersack and Littmark [6]; ICRU Report 49 [7]; and SRIM 2003 [8]. The latter two give the best agreement.

Table C4 shows the positive effect of the CAB correction (which is very hard to discern generally): the corrections decrease Δ by 4 % and bring SRIM very close to the data.
The following comparisons with the tables MSTAR [9, 10], SRIM 2003 [8], and ICRU Report 73 [11] have been taken from [12]. Comparisons with additional tables can be found in [11]. Separate results for the various ions (as compared to MSTAR) can be found in [10].

Evidently, MSTAR and SRIM describe the data about equally well. For the ICRU table, the agreement at low energy is generally worse.
These data were rejected because of obvious discrepancies with other data for the same Z1 – Z2 – combination.

The list shows the compounds treated up to now (1 Dec. 2005) in our statistical analyses. The list gives names, formulae, short file designations, physical state, the Bragg corrections (in percent) according to SRIM 2003 (for p and α), and an identification number. Compounds with ID < 300 are in the ICRU 49 table. A “g” in the "state" column indicates that the substance is gaseous at normal temperature and pressure (NTP). Many substances that are not gaseous at NTP, have been measured at reduced pressure in gaseous form; this is indicated by a "v" at the end of the file name, and a "g" in the "state" column.
