Present Situation of Diffracted X-ray Radiation and Resonance (Coherent) Transition Radiation Induced by High Energy Charged Particles in Frequencies Region Exiding Atomic one

摘要

The review is devoted to the modern investigations of electromagneticradiation by relativistic charged particles propagating with constant velocitythrough the periodic media. Two examples of radiation are considered in thisreview, the first corresponds to the Bragg scattering of charged particlespseudophotons in crystals, the second one to the Fresnel scattering ofpseudophotons in periodic medium. Both examples play essential role inconstruction new compact tunable sources in X-ray region.
