| Abstract: | The cluster-Bethe-Lattice method is applied to a model two-band alloy. Intra-atomic Coulomb interactions are taken into account within the Hartree-Fock approximation. Charge transfer effects are treated self-consistently. A numerical calculation with parameters appropriate for the AuAg system yields results which are in qualitative agreement with experiments. |
