It is shown that the dependence of relaxation time for the kinetic energy of the incident electron on the edge dislocation is characterized by electron oscillations whose period decreases in a longitudinal magnetic field, and the relaxation time increases due to the hybrid quantization. It was found that the above mechanism of scattering may be significant in comparison with the scattering on LA-phonons and on the random rough boundary for quantum wire, while the temperature range of its effectiveness is determined by the occupation probability of acceptor centers in the dislocation line. The charge state of the dislocation line can significantly affect the width of the temperature range, where the scattering of electrons on the edge dislocation is dominated.
