Practical calculations of stopping powers for intermediate energy electrons in some elemental solids
چکیده انگلیسی
This study presents calculation results of the stopping power (SP) of electrons of kinetic energy from 10 eV to 100 keV for some elemental solids. The method is based on utilization of the modified Bethe-Bloch SP expression and analytical expression for effective atomic electron number and effective mean excitation energies of target atoms, and for effective charge of incoming electrons, Sugiyama's semi-empirical formula is embedded in the formula. An analytical expression for the practical SP calculations using Bethe approximation and Thomas-Fermi model of atom is taken from an pervious study and the calculated results of the SPs from this formula for electrons in some elemental solids, such as Al, Si, Cr, Ni, Cu, Ge, Pd, Ag, Pt, and Au, are calculated and rigorously compared with experimental data, Penelope code results and with results of other calculations such as the non-relativistic Bethe SP equation and the empirical modification of the Bethe equation by Joy and Luo. The results are found to be in good agreement for some targets but some limited agreement for some energies and targets is also observed.
