Possibility of controlled variation of the atomic crystal structure of paratellurite by means of the excitation of an ultrasonic standing wave

The possibility of controlled variation of the atomic crystal and electronic structures of a paratellurite crystal under the excitation of intense ultrasonic vibrations has been studied. The resonance diffraction of synchrotron radiation has been used for the first time for such a study. The effect of ultrasonic modulation implemented by means of an acoustic standing wave excited in a high-$Q$ TeO$_2$ resonator on the structure of the forbidden X-ray 100 reflection has been experimentally demonstrated.
