抄録

Anomalous diffusion coefficient is evaluated by using result of the renormalized perturbation theory for the turbulent collision. Two cases are investigated for light impurity ions, one in the plateau regime and the other in the banana regime. Time evolution of the wave speetrum is solved numerically and the diffusion coefficient is determined, by taking the density gradient of impurity ions in the same direction as that of the bulk plasma. Even with a small concentration of the impurity the diffusion coefficient takes a smaller value for both regime cases.
