Abstract

An approach is presented for theortical calculations of inelastic losses in solids over a broad energy range. The method is based on a many-pole model dielectric function, which is derived from ab initio calculations of optical constants using a real-space Green s function formalism. The approach yields inelastic mean free paths (IMFP). Using the same dielectric function model, we also obtain relativistic stopping powers for high-energy electrons. The results are consistent with semi-empirical approaches and with experiment.
