In order to study effects of choice of alloy potentials on the band structures ofbinary alloys, calculations of the spectral density and complex energy bands ofNb. .Mo, are carried out in the average 7-matrix approximation scheme. Thealloy potentials are constructed in three ways by using tlte muffin-tin potentialsof pure Nb and Mo. Choice of the alloy potentials remarkably affects the im-aginary parts of the energy eigenvalues, while the band structures themselvesremain almost unaffected. For alloy systems such as Nb-Mo, it is found that,with carefully constructed potentials, the average r-matrix approximation schemecan give as good results as those obtained by the coherent potential approxima-lion scheme.
