摘要：
The effect of particle collisions on effective transport in two-dimensional electrostatic plasma turbulence is studied analytically in the framework of a test particle approach. We show that an amplification of the diffusion coefficient can be produced by the combined effect of collisions and trajectory trapping in the structure of the stochastic potential.
