摘要

The oscillatory profile of diffuse scattering of ordered crystal PbF₂ is observed by time-of-flight (TOF) neutron scattering measurement. The theoretical expression of diffuse scattering intensity including the correlation effects among the thermal displacements of atoms is used to analyze the diffuse scattering profile of PbF₂. The theoretical expression is effective for the analysis of the diffuse scattering data by the TOF measurement.
