Neutron diffraction by an absorbing vibrating InSb crystal

Following our recent paper [Lukás, Kulda, Mikula, Sedláková, Alexandrov & Vrána (1991). Acta Cryst. A47, 166-169], a comparison of the dynamical description of diffraction by an absorbing elastically deformed perfect crystal with the experimental data taken at diffraction by a longitudinally vibrating InSb crystal is presented. The comparison is performed on the time-dependent integrated intensity spectra for different values of the vibration amplitudes. The applicability of the analytical formulas derived earlier by two of the authors for an arbitrary homogeneous deformation is in this case fully approved by the good agreement between the theory and the experiment.
