Electron elastic backscattering probability and inelastic mean free path.

We study the angular distribution of electron elastic backscattering probability, using the Oswald-Kasper-Gaukler (OKG) model and Monte Carlo simulation. The present results are consistent with experimental data and other theoretical calculations. We also propose an approach that makes the OKG model applicable to determine electron inelastic mean free paths for compounds. We apply the OKG model with the proposed approach to zinc oxide (ZnO) and cerium dioxide (CeO2).
