摘要：

The diffuse scattering pattern of high temperature phase of CuAgSe was investigated by X-ray powder diffraction measurements at 523 K. The wide and strong peak of diffuse scattering appeared around 2 theta similar to 35 degrees. There were two contributions to the oscillatory diffuse scattering, one was the short range order of cations. The other was the correlation between thermal displacements of anion-cation and cation-cation pairs. The theoretical treatments of the diffuse scattering including the correlations among the thermal displacements of atoms were described.
