Synchrotron study of the dynamical effects in the LVV auger transitions in the first-row transition elements

Abstract

The intensity ratio between L₂-M₄₅M₄₅ and L₃-M₄₅M₄₅ spectral features for both Fe and Co indicates significant tranfer of intensity from L₂- to L₃-M₄₅M₄₅ region due to Coster-Kronig L₂-M₄₅M₄₅ transition. The L₂-L₃M₄₅ transition can be suppressed by turning the photon energy between the L₂ and L₃ thresholds; however, the L₃-M₄₅M₄₅ spectral shapes for Fe and Co do not change very significantly even at these photom energies unlike the cases of Ni, Cu and Zn, thus establishing that the M₄₅-hole decays predominantly before the L₃-hole Auger decay in the early transition elements in contrast to the late ones.
