Theory

  In the direct simulation model, all possible relevant scattering events are simulated separately. This approach requires accurate models describing these fundamental processes. Elastic scattering is well described by the partial wave approach of Mott. For inelastic scattering a distinction is made between ionization processes and other inelastic processes (mainly plasmon losses, inter- and intraband transitions). Latter inelastic scattering processes (in further referred to as inelastic) are described by the dielectric approach proposed by Penn ([],equation gif). The innershell ionization cross sections and associated energy losses are calculated with the expression by Gryzinsky ([Gry65], formula A.15).
