X-ray optical processes in solids—absorption, fluorescence and resonant scattering—are modeled within a band-structure-based approach to describe electron states. The theory goes beyond a simple one-electron treatment by considering self-energy corrections for 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 are discussed. Theoretical results for all three types of x-ray spectra (absorption, fluorescence and resonant scattering) are presented and compared to experiment. Results are presented for diamond, graphite, NaF and Al. © 2000 American Institute of Physics.
