Abstract
We consider conduction electrons in two different orbital channels int eracting with a spin-1/2 impurity via isotropic spin exchange. The exc hange is the same for both channels, but a crystalline field breaks th e orbital symmetry. The finite size corrections to the ground-state en ergy are derived from the Bethe ansatz equations and used to discuss t he magnetoresistivity.
