Landau levels and radiation by electrons at planar channeling in monocrystals

Magnetic field effect on the movement and radiation by electron under plain channeling in a monocrystal is considered. It is shown that in the subbarrier region of transverse energies discrete levels similar to Landau levels appear instead of the continuous spectrum. Spectral composition and intensity of anomalous and normal waves are calculated. Possibilities of electron radiation observation from the Landau levels are discussed
