Abstract

The diffuse x-ray scattering of Cu3Au has been studied utilizing contrast vari- ation by resonant scattering. The data has been analyzed in view of separating (i) individual atomic pair-displacements and (ii) to distinguish mere size-effects from those due to charge transfer. A particularly interesting aspect of the latter approach is that higher order correlations related to charge transfer such as Fermi- surface effects can also be revealed in the pattern of displacement scattering.
