Abstract

Interference among Bragg beams and effects of polarization state mixing in a multibeam diffraction process leads to a new method of determining noncentrosymmetric phases when an elliptically polarized x-ray beam is used. This idea is demonstrated by an experiment on a GaAs single crystal. With a structurally known noncentrosymmetric crystal the same method can be used to measure the degree of a circular polarization.
