Compound atom theory of anomalous rare earth intermetallides

The problem of interaction of the Fermi-liquid type excitations with unfilled f- and d-shells of rare earth ions in the intermetallides is reformulated in terms of resonance scattering theory in close analogy with the multichannel theory of the compound nuclei. The resonance scattering is accompanied by excitations of atomic quasicontinuum modes playing the same role as the slave-bosons in the conventional approach, and this interaction with the intra-atomic modes of f-ions is considered as essentially a local mechanism of the heavy fermion and mixed valence behavior.
