The wave function of an electron of energy 10 MeV less than or equal to E l
ess than or equal to 100 MeV axially channeled in a Longitudinal hypersonic
superlattice has been obtained within the framework of a quantum mechanica
l approach. Conditions for the resonant influence of the hypersonic wave ex
cited in the single crystal on the quantum states of the channeled electron
have been deduced.
