Multiplet-splitting of the quasi-atomic-like core-valence-valence (CVV) Auger spectra of zinc metal is calculated rnby explicitly considering the so-called hole-hole interaction in the final valence states of the Auger transition.rnWe assume that before the Auger transition occurs, the occupied valence states relax to screen the core-hole rnwhich results in a redistribution of the valence electrons, in particular within the atom that contains a hole in the rncore. The supercell method is used to calculate the electronic states concerned by the Auger transition, which is rnaccomplished by the self-consistent full-potential linearized augmented plane wave method. In each supercell, one rnatom is considered to have a core-hole and many others without it. Due to relaxation and screening, the valence rnstates at the site of the Auger transition are more localized compared with those in the ground-state metal. The rnmultiplet peaks of the quasi-atomic-like CVV Auger spectra of zinc metal are obtained by calculating the Auger rntransition matrix elements between the referred states.
