Abstract
Thermal diffuse scattering (TDS) from single crystals of barium strontium niobate (SBN) and from a partly deuterated single-crystal of tris(sarcosine) calcium chloride (TSCC) measured on the time-of-flight (TOF) Lane single-crystal diffractometer DN-2/IBR-2, Dubna, Russia, are presented. Various characteristic distributions of the TDS were measured and could be interpreted for the elastically (nearly) isotropic SBN crystals as well as for the anisotropic TSCC sample in accordance with the theory. The velocities of sound propagation are determined in both cases. Temperature-dependent changes of the TDS are qualitatively analysed for SBN crystals.
