- Title
On the theory of X-ray acoustic resonance in the Bragg geometry.

- Abstract
A theory of X-ray acoustic resonance in the Bragg geometry is developed as applied to triple-axial X-ray diffractometry. In contrast to existing approaches, transverse ultrasonic oscillations propagating in the surface region of a crystal are considered in the model of a Rayleigh surface wave. Numerical simulation of reciprocal space maps and their cross sections is carried out depending on the ultrasound amplitude. The influence of multiple scattering on diffraction profiles of various diffraction orders under X-ray acoustic resonance conditions is demonstrated.
