The Dispersion Analysis of X-Ray Scattering under Asymmetric Laue-Diffraction Conditions in the Case of Elastically-Bent Crystal

摘要

In the case of asymmetric Laue diffraction, the dispersion analysis is made for the bend of atomic planes in the parabolic-cylinder form. The extreme cases of strong and weak deformations are examined in details. When the strong deformations (corresponding to the kinematical diffraction regime) take place, it is inferred that the increasing asymmetry of scattering leads to the phenomenon of 'smoothing' of deformation, effectively so that the influence of deformation over scattering is decreased. When the crystal thickness is much more than extinction length, it is shown that this phenomenon can take place during dynamical-diffraction regime too.
