Abstract
Ce-based systems were studied by means of x-ray photoelectron spectroscopy. The density of states was calculated by the TB-LMTO-ASA and APW+LO band methods. A correlation was found between 4f level localization and x-ray photoelectron spectra with characteristics of the heavy fermion state. It was shown that a high value of interatomic interaction is characteristic of Ce-based systems with heavy fermions under normal conditions.
