Abstract

It is difficult to describe correctly the electronic structure of a system in which correlation of localized electrons and hybridization of these electrons with extended states both are important. The Anderson impurity model has been used in several forms to give insight in this problem1,2. However, in the Anderson Hamiltonian the screening of f- and core electrons by polarization is neglected. We show in this contribution that in some cases the approximation can lead to erroneous results for the value of the f-occupancy in the ground state <nf>, deduced from photoemission data.
