Abstract
The single-site coherent-potential approximation for substitutional disordered alloys is extended to include the effects of random off-diagonal elements and of the formation of clusters. Our results are in good agreement with the exact numerical computations performed on a one-dimensional system over most of the energy region.Keywords
