Kß x-ray emission of divalent nickel compounds

Abstract

The Kß x-ray emission spectra of divalent nickel compounds are analysed with both the crystal field multiplet model and the charge transfer multiplet model. The spin-dependent Kß x-ray emission spectrum is calculated and the charge transfer effect is rather different in nature for spin-up (²A2) and spin-down (4A2) symmetry states. In case the of a spin-up symmetry state it is shown that multiples-induced mixing strongly affects the spectral shape. It is argued that renormalized crystal field multiplet calculations remain a useful approach to describe the Kß x-ray emission spectral shape.
