Frequency-angular characteristics of quasicharacteristic radiation in the case of plane channeling of relativistic electrons in crystals

Abstract

In this paper, a theoretical study of the frequency-angular characteristics of short-wavelength quasicharacteristic radiation is presented. This radiation is produced as a result of transitions between the energy levels of transverse motion in the case of plane channeling of relativistic electrons in various crystals. Detailed numerical analysis shows that short-wavelength radiation, the parameters of which remain unchanged in a broad range of particle energies, exists at small angles in the domain of existence of the normal complex Doppler effect.
