Auger widths of levels

Abstract

The partial Auger width corresponding to the transitions from the considered level to all levels of particular configuration is presented in the form of the diagonal matrix element of an effective operator. The general expressions for such an operator in the case of two main types of Auger transitions are obtained. They are used to derive the explicit formulae in some special cases as well as to investigate the term-dependence of the Auger width. The types of configurations which levels have equal Auger width or, on the contrary, strongly depend on many-electron quantum numbers, are indicated.
