Abstract
The first sixteen moments of the density of states of the d electrons in CuNi alloys have been calculated in the tight-binding approximation and analysed using continued fractions. No s-d hybridisation has been taken into account and the disorder has been assumed to complete and diagonal. The densities of states are given for atomic Cu concentrations equal to 0.1, 0.5 and 0.9 and are compared with the CPA computations.Keywords
