AbstractIn the present paper, we re-visit a well-known problem in diffusion theory, namely the 90° scattering problem. We use a test-particle code to compute the pitch-angle Fokker-Planck coefficient at 90° for different values of the turbulent magnetic field strength and the magnetic rigidity. We consider a slab model and compare our numerical findings with the analytical result provided by second-order quasilinear theory. We show that the latter theory accurately describes 90° scattering. We also replace the slab model by a more realistic two-component model to explore the influence of the turbulence model on 90° scattering. © 2014 AIP Publishing LLC.
