Measurement with improved resolution of X-ray diffuse scattering from short-rangeordered Cu-39, 53 and 59 at.'3Au alloys has been carried out by photographic methodusing tiny single crystals. In the pattern taken with both crystal and film keptstationary, diffuse scattering maxima appear as satellite crosses accompanied by streaksat the 110, 210 and other equivalent positions. The separation between the diffusesatellites shows a composition dependence, decreasing with increasing gold content.Fermi-surface-imaging idea suggests that this decrease is attributed to a change in the(110) diameter of the Fermi starface of the alloys. Fourier transformation of theintensities of one of the diffuse maxima gives an interatomic correlation function, whichsuggests the existence of an antiphase relation between the local Ll. ordered regionsseparated by 28 A.
