Abstract
The authors calculate the ground state susceptibility chi 0, 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 chi 0 and TK, to first order in 1/N.Keywords
