Photoelectron spectra of core electrons from palladium—silver alloys

For a number of PdAg alloys the photoelectron spectra of the core electrons are studied in a systematical way. The role of the so‐called extrinsic and intrinsic losses, satellite structures, and line‐shapes is to be discussed for 3p and 3d lines. Existing theories are discussed for the given cases. A multi‐electron mechanism for explaining satellite structures is proposed. Asymmetry of the Pd 3d lines is studied and a strong dependence on the density of states at the Fermi energy is found.
