Abstract Recent progress in descriptions of photoelectron spectra is reviewed with emphasis on cases where the one‐electron and quasiparticle approximations break down and the hole level becomes spread over a number of discrete lines or a continuum or both. Unifying aspects and similarities between interaction processes in atoms, molecules, and solids are stressed.
