Abstract
A cluster theory based on the continued fraction method has been used for the density of states of the d electrons in Cu-Ni alloys. No s-d hybridisation has been taken into account and the tight-binding hopping matrix elements used in the computations have been derived from existing values of the Slater-Koster parameters for the alloy. The results show that, while the method gives a majority band less detailed than in CPA computations the structure of the minority band of Ni, smeared out by CPA, is well reproduced.Keywords
