Abstract : The dawn-to-dusk magnetospheric electric field E breaks the pitch-angle degeneracy of particle drift shells in a magnetic-dipole field. For particles of sufficiently large kinetic energy T, the expression for the associated radial-diffusion coefficient is given. The coefficient of pitch-angle diffusion is roughly half the reciprocal lifetime. In the absence of pitch-angle scattering, the electric splitting of drift shells constitutes an important adiabatic phenomenon. (Author)
