The following computer programs for stopping power are available on the internet:
SRIM, for all ions and targets, including compounds by means of Bragg rule and an option for compound correction. Authors: J.F.Ziegler and J.Biersack. The last version up to now is SRIM-2013.
MSTAR, for Li to Ar ions in different targets. Authors: H. Paul and A. Schinner. Results of MSTAR in tabular form can be found in H. Paul and A. Schinner, Atomic Data and Nuclear Data Tables 85 (2003) 377.
CasP (version 6.0, March 2021), for all ions and targets, atoms and compounds. CasP is Convolution approximation for swift Particles, by Grande and Schiwietz. Reference: G. Schiwietz and P.L. Grande, "Stopping of Protons - Improved Accuracy of the UCA Model", Nucl. Instr. and Meth. B 273, 1-5 (2012), F. Matias et al, J. Phys. B 50, 185201 (2017).
DPASS (version 21.06, Feb 2020), for ions Z=1 to 92 in targets Z=1 to 92. DPass code is "Binary theory of electronic stopping", by Sigmund and Schinner. Reference: A.Schinner and P.Sigmund, "Expanded PASS stopping code", Nucl. Instr. and Meth. B 460, 19-26 (2019).
PSTAR and ASTAR, for protons and alphas in different targets. Author: M. J. Berger, NIST, Report NISTIR 4992 (1992).
ATIMA, for protons and heavy ions, and specific kinetic energies from 1 keV/u to 450 GeV/u. Program developed at GSI by H.Geissel and C.Scheidenberger. See more details in H. Geissel, C. Scheidenberger, Nucl. Instr. and Meth. B136 (1998) 114.
