Abstract

Ag 3 x-ray absorption and 3−4,54,5 Auger electron spectra have been measured and simulated for a variety of x-ray electric-field polarization and Auger electron emission directions. The theory relies on density-functional theory, use of the Bethe-Salpeter equation, atomic multiplet theory and a simplified model for the Auger line shape and its dependence on photon energy. Based on all of the above, we have found a means by which partial densities of states for 2, and symmetry partial wave channels at the Ag site can be deduced from measurements with minimal theoretical input.
