Abstract
A general semi-empirical method has been developed to calculate Auger electron energies within an intermediate-coupling framework. The required Slater integral values and an adiabatic relaxation correction term are obtained from polynomial expressions determined by least-squares fitting to relativistic atomic Hartree-Fock data calculated for closed-shell atoms. This information is combined with experimental electron subshell binding energy data to determine the line energies. Unlike all previous semi-empirical approaches the model proposed does not require any fitting to experimental Auger energies. Furthermore the method is applicable to all classes of Auger transitions. The results for K-LL energies determined within an intermediate-coupling framework, with and without configuration-interaction effects being included, are presented. The predictions are in good agreement with known experimental values.
