摘要：

The influence of the valence band shape and of the 5d band shape on the Ce4+ L-3 X-ray absorption edge spectrum is checked for Ce compounds in the frame of the Anderson impurity model. It is found that the band shapes may significantly modify the spectrum and the parameters of the calculation, especially in the case of a Ce-doped oxide. The example of Ce-doped yttria spectra calculated with the yttria valence band shape is given at the end of the paper. (C) 1997 Elsevier Science B.V.
