Abstract
The authors calculate the ground state susceptibility chi0, to leading and next-leading order in a 1/n expansion, for the N-fold degenerate Anderson model in the integral valent limit. From this and perturbational results they are able to calculate the Wilson numbers W(N), which relate to chi0and TK, to first order in 1/N.Keywords
