CPA treatment of superconducting alloys

A theory for superconducting alloys is formulated on the basis of the Coherent-Potential-Approximation (CPA) to treat the disorder problem. Using a simple model for the density of states, the transition temperature is calculated as a function of the concentration and compared with experiments.
