Pitch-Angle Dependent Perpendicular Diffusion of Energetic Particles Interacting With Magnetic Turbulence

Abstract

We employ a test-particle code to explore diffusion of energetic particles interacting with the solar wind plasma.The first time we investigate the pitch-angle dependence of perpendicular diffusion for different parameter regimes.These results are important for numerical solutions of the pitch-angle dependent Cosmic Ray Fokker-Planck equa-tion. We compare our finding also with predictions made by analytical theory.
