“…Experimental studies of PXR from beams with energies from 25 to 900 MeV interacting with several types of single crystals have generally verified the predicted angular distribution, bandwidth, and polarization of PXR [12][13][14][15][16][17][18].…”

“…Transition radiation is not a single field which undergoes diffraction in the considered case. Another part of the emission in the Bragg direction, known as parametric x-ray radiation (PXR) [2][3][4][6][7][8][9][10][11], comes from the diffraction of virtual photons constituting the particle's proper field inside the crystal. At high particle energies its distribution has the angular width ∼ω p =ω (where ω is the radiation frequency) which significantly exceeds the one ∼1=γ of DTR.…”

The process of diffracted x-ray transition radiation by a high-energy "half-bare" electron in a crystalline target is considered in Bragg geometry. The electron is supposed to appear in the mentioned state, in which the field around it is significantly suppressed comparing to the equilibrium Coulomb one, in the result of preliminary penetration through an upstream amorphous target situated on some distance from the crystal. It is shown that the process of the electron's field regeneration after its exit from the upstream target dramatically modifies both the diffracted transition radiation angular distribution and its total yield making them dependent on the distance between the targets. Analytical expressions for these quantities, as well as their simple approximations, are derived. Almost arbitrary crystal orientation is considered. Special attention is drawn to the case of backward radiation geometry when the emitted radiation has to penetrate through the upstream target on its way to the detector.
