The coherent-pseudopotential approximation for the electronic structure of disordered alloys with constituents having many subbands has been discussed. A single-site and single-band approximation is used and coupled with two self-consistent approaches. In the first approach a distinct self-energy is assigned to each subband and in the second a common self-energy is attributed to all the subbands. Both the approaches have been applied to the calculation of densities of states of Cu-Ni alloys over the whole range of compositions. Results are presented for the total density of states and the partial density contributed by each constituent.
