Anisotropic Cosmic Ray Diffusion Tensor in a Numerical Experiment

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The propagation of galactic cosmic rays in a model magnetic field, which is a composition of an isotropic turbulent field with the Kolmogorov turbulence spectrum and a regular constant field, is studied numerically. The dependence of the diffusion tensor on the particle energy is studied. The article shows that with decreasing energy, the anisotropy of transport increases.
