The theory of inelastic losses in x-ray spectra has long been of interest. These losses include plasmons, particle-hole pairs, Debye–Waller factors, and other many-body effects that damp and shift the spectra. The losses give rise to additional features known as satellites that are not present in independent electron or quasi-particle (QP) approaches.
