摘要：
Large hybridization effects are observed in 4f resonant photoemission spectra of Pr and Nd transition-metal compounds that lead to energy splittings of several eV varying strongly with the composition of the compounds. The phenomena are described quantitatively in the framework of a single-impurity Anderson model. Large splittings of the 4f emission are obtained, if the energy position of the expected 4f electron-removal state coincides with maxima of the valence-band density of states. For the 4f(n) ground states, admixtures of 4f(n+1) states of the order of some percents are obtained.
