Modeling final-state interaction effects in inelastic X-ray scattering from solids: resonant and non-resonant

We present resonant inelastic X-ray scattering calculations that realistically incorporate intermediate-state electron–core hole interactions and final-state electron–valence hole interactions. Intermediate-state interactions primarily affect the total fluorescence yield, whereas final-state interac...

Description
Summary:We present resonant inelastic X-ray scattering calculations that realistically incorporate intermediate-state electron–core hole interactions and final-state electron–valence hole interactions. Intermediate-state interactions primarily affect the total fluorescence yield, whereas final-state interactions can change the relative strengths of spectral emission features. This is especially true in systems with strong valence–hole exciton effects. We also consider non-resonant excitation of core electrons. This work considers resonant scattering from B 1s electrons in cubic boron nitride (cBN) and hexagonal boron nitride (hBN) and non-resonant scattering from Mg and O 1s electrons in MgO, and compares theoretical results to experiment.
