Abstract

We estimate the relative contributions of the decay channels arising from various Coster-Kronig (CK) and initial-state shake processes to the satellite intensity accompanying the $_L_2-$ and $L_3-M_{45}M_{45}$ Auger spectra of Cu. While the intensity ratios between the $L_2-$ and $L_3-M_{45}M_{45}$ spectral features in Fe and Co also exhibit pronounced effects of the Coster-Kronig $L_2-L_3M_{45}$ transition, the CK process does not lead to the formation of distinct satellites in the $L_3-M_{45}M_{45}$ spectral region, in contrast to the case of Cu. This fact establishes that the $M_{45}$ hole generated by the CK transition primarily decays before the $L_3-$ hole Auger decay in the 3d transition elements up to Co.
