STOPPING POWER OF DIAMOND FOR LOW ENERGY ELECTRONS.

Theoretical models used to describe the interaction of electrons with the valence band of insulators are discussed. Results for the application of these models to calculate stopping power and mean-free path of low-energy electrons ( less than 10 keV) in diamond are presented. The influence of core polarizability, oscillator strength coupling between core and valence electrons, and exchange corrections is included. The contributions to the mean-free path and stopping power from ionization of inner shells have been evaluated from sum-rule-constrained classical binary-collision model.
