The diffusion coefficients, both parallel and perpendicular to the background magnetic field, are calculated using test particle simulations of the transport of energetic particles in the heliosphere. We consider strong static, low-frequency solar wind turbulence. Two models for the magnetic field turbulence are examined: slab turbulence with and without intermittency of the turbulence amplitude. Results show that the diffusion coefficients parallel and perpendicular to the background field are weakly dependent on the power index (q) of the probability distribution function of the intermittency within the chosen interval 1.68 ≤ q ≤ 1.8. The diffusion coefficients however, show a strong dependence on the scale length of the intermittency, and are strongly reduced for smaller scale intermittency.
