The phenomenon of electron channelling in a crystal affected by dislocations was considered. Previously, consideration had been given to the quantum aspects of positron channelling in a crystal bent by dislocations, where the effects of longitudinal motion of the particle were considered together with the transverse motion. The effective potential for the electron case was found for the two regions of dislocation-affected channel. There was a considerable shift in the potential minima due to dislocations. The frequency and the corresponding spectrum of the channelling radiation, due to electrons channelling through the perfect channel and the two regions of dislocation-affected channel, were calculated. The spectral distribution of radiation intensity changed with the dislocation parameters. The continuity of wave-functions and their derivatives was used at the three boundaries, and reflection and transmission coefficients were found by using these boundary conditions in the same way as in the positron case.
