We present a first-principles scheme for calculating the dynamic structure factor and inelastic x-ray scattering double-differential cross section for the valence electrons. The electron-hole interaction is taken into account. Theoretical results are

The dynamic structure factors S(q,ω) of diamond and LiF have been measured using inelastic x-ray scattering. The experimental data are compared to results of ab initio calculations, which take into account the interaction of the excited electron with the
The much-discussed electron-hole attraction in resonant inelastic x-ray scattering is analyzed. Its effects on fluorescence yields and emission features are studied. While the attraction can influence both properties of fluorescence, in some cases the

Optics has found an extremely wide range of applications in industry and science, and the properties of the materials that make up optical instruments are key to their performance. Examples include glass for optical instrumentation such as telescopes and

X-ray optical processes in solids--absorption, fluorescence and resonantscattering--are modeled within a band-structure-basedapproach to describe electron states. The theory goes beyond a simpleone-electron treatment by considering self-energy corrections
