Abstract

The heavy-fermion system Ce

{Cu}_{6}

has been studied by photoemission and inverse photoemission spectroscopies. The spectra are analyzed within the Anderson single-impurity model and the relevant parameters deduced from the comparison between theory and experiment. This oversimplified formalism explains why, even with our markedly improved experimental conditions, the manifestations of heavy electrons around the Fermi level still cannot be discerned in the spectra.
