Resonant Influence of Hypersound on the Radiation of an Axially Channeled Electron

The spectral intensity of the radiation emitted by an axially channeled
electron in a single crystal excited by a longitudinal hypersonic wave
propagating along the channeling direction has been calculated for the
energy range 10 MeV £E£100 MeV.
It has been shown that under the influence of acoustic vibrations excited
in the single crystal a resonant intensification of the electron
channeling radiation, a variation of its spectral distribution as well as inverse
radiative transitions are possible.
