In our previous papers [1-4], where we studied the interaction of electrons with spatially localized lower hybrid waves, we considered as zero approximation the unperturbed constant velocity of electrons, for simplicity circulating along a circular magnetic field line. The basic stochastic interaction appeared at nonlinear resonant frequencies of the interaction. In these papers we anticipated the possibility of accelerating electrons to velocities higher (even relativistic) than predicted by quasi-linear theory. The paper [5] was perhaps the first paper, in which this possibility was experimentally established. In reference [6] wewe tried to support this phenomenon again by means of theory and numerical simulation. Despite the fact that large acceleration was found in [6], we were not able to reach the experimentally detected values due to lack of overlapping of resonances for higher velocities.
