Observation of the elastic quasi-mosaicity effect in bent silicon single crystals

A considerable elastic quasi-mosaicity effect has been observed upon the diffraction of x-rays on a bent silicon single-crystal plate. It has been shown that the effect depends on the choice of reflecting crystallographic planes and the orientation of the plate cut. The effect can be applied to improve the characteristics of silicon single-crystal monochromators of electromagnetic radiation and silicon single-crystal deflectors of charged-particle beams.
