摘要：
The influence of the ultrasonic wave on the dynamic diffraction of the Mössbauer γ quanta in the perfect Si crystals has been studied. Both the scattering intensities and the diffractional Mössbauer spectra for different reflections and ultrasonic frequences νs have been measured. Some unusual results such as the enhancement of the elastic scattering at high νs with ultrasound amplitude growing and non-exponential decrease of the Debye-Waller factor (connected with ultrasonic phonons) at low νs have been obtained. The experimental data are in good agreement with the theoretical calculations. © 1990 J.C. Baltzer A.G. Scientific Publishing Company.
