Electron pitch-angle diffusion: resonant scattering by waves vs.nonadiabatic effects
Abstract : In this paper we investigate the electron pitchangle
diffusion coefficients in the night-side inner magnetosphere
around the geostationary orbit (L 7) due to magnetic
field deformation. We compare the effects of resonant
wave–particle scattering by lower band chorus waves and the
adiabaticity violation of electron motion due to the strong
curvature of field lines in the vicinity of the equator. For
a realistic magnetic field configuration, the nonadiabatic effects
are more important than the wave–particle interactions
for high energy (> 1 MeV) electrons. For smaller energy,
the scattering by waves is more effective than nonadiabatic
one. Moreover, the role of nonadiabatic effects increases with
particle energy. Therefore, to model electron scattering and
transport in the night-side inner magnetosphere, it is important
to take into account the peculiarities of high-energy electron
dynamics.
