ArgonKLLAuger Spectrum: A Test of Theory

Abstract

The relative intensities of the argon $\mathrm{KLL}$ Auger transitions, measured with an accuracy of better than 10%, are found to agree well with recent theoretical predictions based on a theory that uses intermediate coupling, configuration interaction, and good wave functions and level energies. Large widths for $K{L}_1{L}_{1,2,3}$ lines suggest high Coster-Kronig transition rates for double-hole configurations $L_1{L}_1$ and $L_1{L}_{2,3}$.
