Leath Department of Physics, Rutgers?The State University, New Brunswick, New Jersey Received 5 February 1968; published in the issue dated July 1968 The connection between Taylor's recent self-consistent calculations of phonon frequency spectra in disordered alloys and those of Davies and Langer in the usual self-consistent-field approximation is established. It is found that Taylor's results are equivalent to summing the same diagrams summed by Davies and Langer, but with proper compensation against multiple occupancy of sites by defects. The recently developed technique of Elliot, Aiyer, and Leath, which self-consistently adjusts the diagram rules to obtain proper compensation, is used. This method is quite general and clearly can be used for other self-consistent calculations is disordered alloys. c 1968 The American Physical Society URL: link.aps.org/doi/10.1103/PhysRev.171.725 DOI: 10.1103/PhysRev.171.725
