RECIPROCAL-SPACE ANALYSIS OF SHORT-RANGE-ORDER INTENSITIES BY THE CLUSTER-VARIATION METHOD

A reciprocal space formulation of the Cluster Variation is used in order to extract effective pair interactions in alloys from experimental short-range order diffuse intensities. The method is applied to the analysis of the short range order contribution to the neutron diffuse scattering of a
