The cross-field electron particle and energy transport for a high ..beta.. thermal plasma is investigated using a magnetostatic particle code. The diffusion process due to magnetic fluctutations alone is observed to have a Bohm-like scaling. However, when both electrostatic convective cells and magnetic fluctuations are allowed, there is interference between the two diffusive processes; the diffusion takes on the character of strong turbulence for the interaction between these static modes. The resulting diffusion is smaller than would be the case when assuming that these modes are independent.
