The multiple‐scattering theory is applied to determine the electronic spectrum of a one‐dimensional binary alloy of spatially non‐overlapping randomly distributed scatterers. A general expression is derived for the alloy density of states using the average‐ T ‐matrix approximation (ATA). Within the framework of the ATA both the complex energy bands and the electronic density of states are calculated numerically for a transition metal like alloy.
