Abstract

The resistivity for an extended two channel Anderson model is calculated. When the temperature decreases, it decreases logarithmically and has T1/2 anomaly at very low temperatures, as seen in some dilute U alloys. The single-particle and the spin excitation spectra are also calculated. The low energy properties and the temperature dependence of the resistivity in the low temperature region are well described by the energy scale deduced from the zero-energy limit of the spin excitation spectrum.
