Abstract

An extended two channel Anderson model, in which an extra local spin couples to the electrons on the localized orbits by the antiferromagnetic exchange, is studied by the numerical renormalization group method. The susceptibility shows low energy divergence inherent to the over screening effect, but the scattering intensity decreases as the conduction electron energy approaches to the Fermi level. This suggests the resistivity will decrease with decreasing temperature as seen in some dilute U alloys.
