摘要：

Monte-Carlo calculations are used to quantify the influence of elastic scattering processes on the shape of electron trajectories in solid matter. Cross-sections for elastic scattering depending on the atomic number Z and the electron kinetic energy are calculated by the partial wave expansion method and the use of Thomas-Fermi-Dirac potentials. As a consequence of elastic scattering, the escape depth decreases to about 80% of the inelastic mean free path. © 1990.
