It is shown that the destabilization of GAM by energetic ions in tokamaks can be accompanied with a considerable energy transfer from these ions to the mode and with the radial displacement of these ions. The possible influence of Alfv?n megahertz instabilities on an energy transfer from the beam ions to the waves in NSTX spherical tokamak is studied. The evaluation of modes count and amplitude, required for forming of stochastic region in a certain energy range, is made. The convection and diffusion of the energetic ions in tokamaks with helical magnetic perturbations has been investigated.
