N2 - The coordination number effects on the effective-pair-interaction of a model binary transition metal alloy are calculated as a function of band-filling and concentration. A six moment expansion along with the maximum-entropy method is used to approximate the density of states of a d-band, nearest-neighbor, tight-binding Hamiltonian, and a decoupled form is used for the higher order correlation functions. We find that the coordination number effects are large. The effective-pair-interaction scales approximately as Z- 3 2 where Z is the coordination number.
