Abstract

The KL2.3 to L2.3L2.3 V Auger vacancy satellite transitions of Mg and Al, which lie to high kinetic energy of the KL2.3 V Auger profile, are analysed using a combination of self-consistent densities of states (DOS) and atomic-like Auger transition rate calculations. The transition rate calculations demonstrate that previous work based on statistical weight arguments is incorrect. The DOS calculations show that the valence s contribution to the local DOS forms a bound state in the presence of a double core-hole state, though the major contribution to the core-hole screening is provided by the local p DOS. The calculation successfully reproduces the spectral profile for the Al transitions, but is unable to account for one of the features in the Mg spectrum.
