It has been shown that the distribution function of high-energy particles satisfies the three-dimensional Fokker-Planck equation for constants of motion. Transport coefficients of this equation are calculated for the axisymmetric tokamak with a circular cross section. The collisional transport of the marginally circulating fast particles is found to be enhanced more than that of the other particles.
