Abstract
The L 2,3 absorption spectra of 3d transition-metal in CrF 3 , MnF 2 , FeF 2 , Co 2 , NiF 2 and ZnF 2 have been measured with a newly designed 10m grazing incidence monochromator. The L 2,3 (2p→3d) “white lines” have been observed in the spectra of CrF 3 , MnF 2 , FeF 2 , CoF 2 and NiF 2 . On the contrary, ZnF 2 does not exhibit sharp white lines, but only weak peaks. This is ascribed to the absence of an empty 3d level. Fine structures of the L 2,3 white lines are interpreted as the multiplet splitting due to the interaction between a metal 2p hole and localized unraired 3d electrons. Observed spectra are comrared with the spectra theoretically calculated by Gupta and Sen and also by Yamaguchi et al .
