On the ratio of the relativistic electron PXR in Bragg and forward direction within Bragg scattering geometry
In the present work, the parametric X-radiation (PXR) and the parametric radiation at a small angle relative to the velocity of a relativistic electron (FPXR) crossing a single crystal plate in Bragg scattering geometry are investigated within the framework of the dynamic X-ray diffraction theory. The expressions for spectral-angular density of the named radiations are derived in the general case of asymmetric reflection. The ratio of the contributions of these radiation mechanisms as a function of reflection asymmetry is considered in this work
