摘要：

The electronic structure of Ce systems with different degrees of hybridization of f electrons with outer-shell electrons and the effect of pressure on the change in the electronic structure has been investigated. A correlation between the parameters of X-ray photoelectron spectra and the magnitude of the heavy-fermion state is established. The total and partial densities of states of atoms were calculated using the TB LMTO ASA method. X-ray photoelectron study of the effect of an X-ray induced vacancy in the inner levels on the shape of the Ce3d spectra for Ce-based systems with different degrees of covalence has been performed. It is shown that there is a relationship between the magnitude of the heavy-fermion state and the intensity of the shakedown satellites in X-ray photoelectron spectra and that the magnitude of the heavy-fermion state decreases under pressure. © Allerton Press, Inc. 2008.
