    "abstract": "The motion of an ion in a coherent lower hybrid wave (characterized by\n|k_parallel| \u003c\u003c |k_perp| and omega \u003e\u003e Omega_i) in a tokamak plasma is studied.\nFor ions satisfying v_perp \u003e omega/k_perp, the Lorentz force law for the ions\nis reduced to a set of difference equations which give the Larmor radius and\nphase of an ion on one cyclotron orbit in terms of these quantities a cyclotron\nperiod earlier. From these difference equations an earlier result [Phys. Fluids\n21, 1584 (1978)] that above a certain wave amplitude the ion motion is\nstochastic, is readily obtained. The stochasticity threshold is given a simple\nphysical interpretation. In addition, the difference equations are used to\nderive a diffusion equation governing the heating of the ions above the\nstochasticity threshold. By including the effects of collisions, the heating\nrate for the bulk ions is obtained.",
