On the mean free path of solar cosmic-ray electrons

The spatial transport of charged particles (electrons) in the presence of pure slab Alfvén waves, pure isotropic magnetosonic waves and their mixture is considered using Monte Carlo particle simulations. We show that the mean free path of solar cosmic-ray electrons strongly depends on the assumed amplitude of MHD turbulence and spectrum but much less on the type of the considered waves. It is demonstrated that in the considered turbulent magnetic field electrons and protons with the same rigidity have significantly different mean free paths, especially in the low rigidity range.
