X-Ray Bragg Dynamical Diffraction in Crystals Weakly Deformed by Ultrasonic Waves

The dynamical diffraction of X‐rays in crystals weakly deformed by transverse ultrasonic waves is investigated. Analytical expressions for the crystal reflection tensor and the modified refractive indexes for the cases of two‐and four‐level X‐ray‐acoustic resonances are obtained. It is shown that th...

Zusammenfassung:The dynamical diffraction of X‐rays in crystals weakly deformed by transverse ultrasonic waves is investigated. Analytical expressions for the crystal reflection tensor and the modified refractive indexes for the cases of two‐and four‐level X‐ray‐acoustic resonances are obtained. It is shown that the modified refractive indexes and reflection tensor depend on the X‐ray‐acoustic resonance conditions. [Russian Text Ignored]
