Above-barrier γ-ray emission by ultrahigh-energy electrons in oriented single crystals
Kononets Yu. V., Tupitsyn I. S.
The spectra of the y-ray emission by ultrafast electrons in a thin crystal are analyzed theoretically for the case in which there is a strong competition between coherence effects and magnetobremsstrahlung effects. This is the first such analysis. The properties of axial and planar coherence resonances which arise in the emission upon the transition from an axial orientation of the crystal to a planar orientation have been studied.
