We report on calculations of the electronic states in disordered Cu/sub c/Ni/sub( 1-c/) alloys based on a complete solution of the coherent-potential approximation for a muffin-tin model of the alloy potential (Korringa-Kohn-Rostoker coherent-potential-approximation (KKR-CPA)). The computational effort required is modest on the scale of that involved in band-structure calculations for many atoms per unit cell. Th calculated densities of states are in good agreement with the results of photoemission and other experiments. The adequacy of previous approximate KKR-CPA and averaged t-matrix calculations is discussed.
