Abstract

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 for electronstates, the perturbation acting on electron states, the perturbation acting on electron states because of a core hole, and, to a lesser degree, lifetime effects for high energy electron states in solids.Aspects of the work that suggest extensions to be made in the future arediscussed. Theoretical results for all three types of x-ray spectra(absorption, fluorescence, and resonant scattering) are presented and comparedto experiment. Results are presented for diamond, graphite, NaF and Al.
