Primary Photoemission Spectra of Gold and Their Relation to the Band Structure

The energy distributions (EDC's) of photoelectrons have been calculated from a relativistic band model for photon energies ranging from 3.7 to 13 eV. The structure elements in the EDC's are related to the band structure, and the regions in k‐space contributing to each peak have been traced out. An EDC‐peak does not in general correspond to a critical point, but has contributions from extended regions in the k‐space.
