Abstract: In this research, a theoretical study for calculation of electronic stopping power with energy (1-12MeV) when passing in some atomic media (Be, C, Al and Cu). The electronic stopping power were calculated using Bethe equation and SRIM 2012 program and also by fitting, and then a semi empirical equation we got for calculating the value of stopping power and after that a comparsion where made with the theoretical results of Bichsel and Getachew. The maximum difference between the the semi empirical calculation and with all results we found using the statistical test ( kstest2) in Matlab program.
