摘要：

We show that the profiles of the Ni K 1,3, x-ray fluorescence spectra of NiF2 and NiO, which were long believed to originate from the multiplet splittings due to an exchange interaction between the x-ray hole and valence unpaired electrons, are clearly interpreted by a charge-transfer effect during the photoionization of one of the 1s electrons. The profiles of the K x-ray fluorescence spectra of NiCl2, NiBr2, and NiI2 are also predicted from the charge-transfer effect. The range of validity of the present theory and its relation to the shakeoff satellites are also discussed. © 1990 The American Physical Society.
