${\mathit{N}}_{6,7}$${\mathit{O}}_{4,5}$${\mathit{O}}_{4,5}$ Auger spectrum of metallic Au

The spectral profiles of the ${\mathit{N}}_{6,7}$ ${\mathit{O}}_{4,5}$ ${\mathit{O}}_{4,5}$ and ${\mathit{N}}_7$ ${\mathit{O}}_{4,5}$ ${\mathit{O}}_{4,5}$ Auger transitions of metallic Au are calculated using a theory that gives a treatment of the influence of the 5d spin-orbit splitting on both the multiplet structure of localized [5${\mathit{d}}^2$] double-hole states and the [5d] single-hole states in the d band. It has not been possible to obtain simultaneous agreement in the kinetic energies and spectral profiles of the Auger spectra. The theoretical profile is in good agreement with the experimental ${\mathit{N}}_{6,7}$ ${\mathit{O}}_{4,5}$ ${\mathit{O}}_{4,5}$ profile when the U${(}^1$ ${\mathit{G}}_4$) correlation energy is taken to be 3.4 eV, though this predicts the spectrum to be 1.2 eV higher in kinetic energy than observed. Possible reasons for this discrepancy are discussed.
