A study is made of turbulent diffusion in a plasma containing high-energy ions. It is assumed that waves are excited which interact resonantly with the electrons and the high-energy ions but adiabatically with the bulk of the ions. For generality, a plasma in which there is a radial electric field is considered. It is shown that the turbulent fluxes of electrons and high-energy ions are directed outward in the plasma, while the motion of the bulk of the ions is inward. This type of turbulent diffusion breaks down at the boundary of the plasma and this produces a radial electric field near the boundary; the strength of this field is estimated. Criteria for anomalous diffusion are investigated. As an example, the results are applied to a thermonuclear plasma. (AIP)
