Diffraction phenomena in spontaneous and stimulated radiation by relativistic particles in crystals (Review)

“…The experiments were conducted for the crystal GaAs. In the papers [95,96] distance between these maxima will increase. The calculated angle of intersection of reflexes (153) and (153) coincides with the measured angle with the accuracy of 10%.…”

“…Recently PXR has been experimentally investigated in the case of multi-wave diffraction [76,[95][96][97]. The experiments were conducted for the crystal GaAs.…”

“…The fine structure of the PXR angular distribution may be experimentally observed while studying the angular distribution near the degeneracy region with the help of a detector having an angular " size AOD$ 10-4 rad and using the electron beam with the angular divergence not greater than AU = _/2AOD0_f< 10-3 rad. Although the obtained results cannot be applied for the explanation of the experimental data [95][96][97] boundary of the surface of a spatially periodic target (see revue [108]). According to [106], this solution, describing the scattering of the plane wave by the target under _he surface diffraction " geometry, can be written in the following form: The spectral-angular distribution of SPXR generated by a particle incident on the crystal at a small angle relative to the crystal surface was obtained in [109].…”

“….According to theory[2,34-.36], PXR is polarized. The papers[88][89][90][91][92][93] are devoted to the investigation of the polarization characteristics of PXR. Let us consider, for example, the results of[89], where the PXR polarization was measured in Si for the asymmetric diffraction geometry and the reflection plane (220), i.e.…”
