Abstract
The Boltzmann equation represents the standard theory for particle transport in random media. It is thus applicable to Auger/photo electrons in polycrystalline solids. In this paper we compare the convential Auger/PES theory, which neglects angular deflection of the emitted electrons, with two scattering models which have been found to be useful in Reactor physics. We find that the conventional Auguer yield formula φ em (θ) = ( Nλ i 4π )cos θ holds approximately qualitatively, but not quantitatively. We also find that, in keeping with Monte Carlo calculations, there is a substantial alteration to the mean depth of analysis relative to the no-scattering model.
