Abstract

A semi-analytical model is proposed for evaluating the electron stopping powers (ESPs) of material media including both elements and compounds in the energy range 1.0 eV–100 MeV. This paper reports details of our calculations using the effective atomic electron number, effective mean excitation energies of target atoms and realistic electron density distribution of the target atoms. This simple formula is capable of generating accurate cross-section for diverse systems. We present here only few simple cases. In comparison with other theoretical predictions, our calculated ESPs for elemental [C, Al, Cu, Pt, Au and Pb] and compound [H2O, C5H5N5O, GaAs, Bi2Sr2CaCu2O8, SiO2 and ZnTe] media agree reasonably well with the experimental findings.
