摘要：
Phenomenon of artificial ultrasound anisotropy is revealed in crystals in the range of X-ray frequencies and an attempt is made to explain this effect theoretically for the case of the Bragg– Laue diffraction. It is established that an isotropic crystal becomes, under action of ultrasound, optically anisotropic like a uniaxial crystal with the optical axis along the direction of the external action; this axis is the symmetry axis and causes birefringence. © Allerton Press, Inc., 2007.
