Green's-Function Method for Energy Bands in Disordered Alloys. II. Band Structure of DisorderedCu3Au

A generalization of the Green's-function method (proposed by the authors in a previous paper) has been used to determine the energy bands of disordered ${\mathrm{Cu}}_3$Au. Energies have been calculated at the symmetry points $\Gamma$, $X$, and $L$ for a series of temperatures above the transition temperature. The crystal potentials and the structure constants are calculated using the short-range-order parameters from the available x-ray data. The results are discussed in terms of the available experimental information for this alloy.
