The diamond surface: III. Differential cross-sections for inelastic scattering

The differential cross-section for K-level ionisation for carbon in diamond and graphite have been derived from the Auger yield. The model is based on exponential attenuation of the outgoing Auger electrons. This model was extended to analyse the K-shell ionisation loss spectra. From the energy dependence of the loss peaks in diamond and graphite, the threshold peak k₀ has been attributed to a single high-angle back-scattering event. The peaks k₁, K₂ and K₃ can be explained in terms of a double scattering mechanism. The loss peak K₅ can be assigned to a triple scattering process.
