【 摘 要 】

It is proposed and implemented a simple method of calculating of the output of the diffracted real photons of bremsstrahlung and transition radiation from perfect crystals of arbitrary thickness up to a primary extinction lengths. It is shown that for small thickness of crystals and observation angles concerning the center of the diffraction of reflex, contribution of diffraction of real photon is comparable with the output of parametric X-radiation. Influence of experimental equipment characteristic on observed characteristics of radiation is discussed.
