摘要：

The Kbeta 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 Kbeta x-ray emission spectrum is calculated and it is shown that 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 multiplet-induced mixing strongly affects the spectral shape. It is argued that renormalized crystal field multiplet calculations remain a useful approach to describe the Kbeta x-ray emission spectral shape.
