Abstract

The degenerate Anderson model with direct and exchange Coulomb integrals, U and J, is found to be integrable and the corresponding discrete Bethe-ansatz equations are obtained. The two interaction enegies, U + J and U - J, are expected to give rise to two distinct energy-scales. The model is related to a variant of the two-impurity Kondo problem.
