Abstract

Influence of 1D strains of different type on unusual x-ray transmission in Ge crystal is studied. The (111,1 11/200), (111,1 1 1/220) and (220,202/022) three-wave Laue diffractions of CuK_(alpha )-radiation are considered at (mu) t>10. Research is carried out by numerical solution of Takagi equation system. It is shown that 1D distortions (equidistant banding, acoustic strain and layer hidden under surface) caused different transformations of two- and three- wave scattering areas. Each of considered strains has its own distinctive influence on multiple unusual transmission. It is explained by various character of interaction between diffracted waves that leads to redistribution of intensity in three-wave area. In some cases the considerable enhancement of three-wave unusual transmission is observed at slight strains.
