Tight-Binding Calculation of a Core-Valence-Valence Auger Line Shape: Si(111)

Abstract
The shape of the L2,3VV Auger line has been calculated for a Si(111) surface and found to be in excellent agreement with the data of Houston and Lagally. By contrast, the experimental line shape scarcely resembles the self-fold of the occupied Si density of states, a fact which the calculation shows to be the result of matrix-element angular momentum dependence and not of "many-body" effects.
