Relativistic Hartree-Fock-SlaterK−LMAuger Intensities: Comparison with Experiments

The relative Auger intensities for the $K-\mathrm{LM}$ group with respect to the $K-L_1{L}_1$ line are presented as a function of the atomic number. The theoretical values are determined by the relativistic Hartree-Fock-Slater atomic model. The available experimental data are in excellent agreement with theoretical relative intensities for $Z\ge 55$. It is concluded that the relativistic effects with a realistic atomic model are as important as effects of the intermediate coupling scheme for medium $Z$ values in the $K-\mathrm{LM}$ group. Additional measurements of the $K-\mathrm{LM}$ relative intensities for intermediate atomic numbers are needed to pinpoint the relative contributions of the relativistic model and the intermediate coupling scheme. Theoretical results are also presented for $\Sigma K-\mathrm{LM} \Sigma K-\mathrm{LL}$ versus the atomic number.
