Abstract
We calculate the effect of bulk- and surface-plasmon dispersion and damping on satellite strengths in photoelectron spectra in x-ray photoemission from core levels of metals. The calculation reveals an appreciable reduction in satellite intensities when compared with predictions of previous dispersionless infinite-lifetime models. Comparison with experimental data shows good agreement for the value of the mean free path for short-range processes and the shapes of satellite lines in the spectra.
