Abstract
The influence of the Coulomb interaction between localf-electrons and conduction electrons on the dynamical properties off-electrons is investigated for the Anderson impurity model. An equation-of-motion technique is used to treat simultaneously the Coulomb interaction and the hybridization. We find that the Abricosov-Suhl resonance remains sharp but is reduced in size while the charge excitation peak of thef-electrons is broadened.
