© 2020, Pleiades Publishing, Ltd.Abstract: In the channeling model, the interaction between relativistic electrons and crystal axes and planes is described traditionally as the motion in an averaged continuous potential. However, real crystal axes and planes consist of individual atoms arranged periodically. The interaction of an electron with periodic heterogeneities is accompanied by the transfer, to the crystal, of strictly quantized portions of the momentum Δ p|| = 2πnћ/d, where n = 1, 2, 3, … and d is the period of the potential heterogeneity arrangement coinciding with that of the crystal lattice in the case of motion along the axis. A photon with the energy (Formula presented.) where E1 is the initial electron energy, is emitted in the case where quantum longitudinal momentum is transferred to the lattice. If E1 ~ 1 GeV or more, a kinetic electron energy of up to 90% transforms into the energy of a single photon during such a process.
