The effect of ultrasound on dynamic diffraction of Mossbauer gamma quanta in а silicon single crystal was investigated. Using Bragg's geometry, the total intensity and its elastic part were measured for the {111), (333), {444) and {220), (440) reflections under the action of high-frequency ultrasound {transverse waves). There is а decrease and oscillation of the elastic scattering intensity as the ultrasound amplitude increases, which contradicts to previously obtained data [1, 2].
