The pairing interacuon V(k-k') is often replaced by ~ constant V (usually taken to be the average of V(k-k') over the Fermi surface/ in the calculation of the superconducting transition ten'|perature Tc in the standard BCS theory. We examine here the effect of an anisotroplc momentum dependeme ~n V(
