Abstract

The radiation emission spectra of polarized photons emitted from charge particle in single crystal are obtained in semiclassical theory in Baer-Katkov-Strakhovenko approximation for planar crystal orientation. The range of applicability of this approximation is estimated by comparing the results with calculations in exact semiclassical theory. Optimal crystal orientations for producing unpolarized and polarized photon beams are also founded.
