Oscillatory diffuse scattering study by time-of-flight neutron scattering

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.
