| Abstract: | Cross sections for the ionization of atomic inner shell by electron&ion impact are one of the mostly process for simulating the hot-electron energy spectrum and yield. Based on the theory of K-shell ionization cross section by electron&ion impact in the relativistic condition, the K-shell and L-shell ionization cross sections of Nb and Ag by electron impact have been computed. Compared with the recently experiment and theory results, the computation results can be used to simulate the hot-electron energy spectrum and yield of laser-plasma. |
