PARAMETRIC X-RAY RADIATION BY RELATIVISTIC CHANNELED PARTICLES

Abstract In this paper, the radiation intensity around the Bragg angle (with respect to a target crystal plane) by relativistic channeled particles is calculated based on the kinematical theory of parametric X-ray radiation (PXR). It is predicted that, in consequence, not only PXR but also Bragg diffraction of channeling radiation will be observed. The latter process is divided into two types by the incident energy. Ordinary photon diffraction occurs in the high energy region and virtual photon diffraction in the low energy region.
