The fundamental tenet underlying the geometrical locus-cluster expansion approach to localized diffuse scattering has been re-examined. It is shown that the theory, as it currently stands, can be successfully applied only to single disordered sublattice systems and has to be expanded when inter-sublattice ordering correlations exist. Such inter-sublattice ordering correlations give rise to cosine fringe contributions to the diffuse intensity which are either incommensurable with respect to the...[Show more]
