Abstract
Transport of energetic electrons in the heliosphere is governed by resonant interaction with plasma waves, for for electrons with sub-GeV kinetic energies specifically with dispersive modes in the whistler regime. We have performed Particle in Cell simulations of kinetic turbulence with test-particle electrons. The pitch-angle diffusions coefficients of these test-particles have been analyzed and compared to an analytical model for left- and right-handed polarized wavemodes.
