Bn. Kalinin et al., Experimental search of parametric X-ray radiation in a silicon crystal at a small angle near the velocity direction of relativistic electrons, NUCL INST B, 173(1-2), 2001, pp. 253-261
At the Tomsk synchrotron measurements of X-ray yield for the energies omega
= 29-53 keV emitted in the forward direction from a perfect silicon crysta
l bombarded by 500-MeV relativistic electrons have been carried out. The co
ntribution of parametric X-ray radiation (PXR) at a small angle near the ve
locity direction of electrons has not been observed. The possible maximum v
alue of this radiation is smaller than 2% of the total intensity of bremsst
rahlung and transition radiation. (C) 2001 Elsevier Science B.V. All rights
