The local atomic arrangements in an Au‐40 at.% Pd alloy were investigated by measuring the X‐ray diffuse scattering from a single crystal. A computer simulation of the short‐range structure was used in the interpretation of the diffuse scattering results. The interpretation indicated a tendency toward the formation of a tetragonal AB long period superlattice which has not previously been observed to occur. The static displacements of the atoms from their average positions were shown to be very small in this alloy.
