Inward radial diffusion and pitch angle scattering in the slot region

The radial diffusion coefficient is calculated for electrons and protons of different energy in the slot region of the earth's radiation belt for various values of McIlwain parameter L and time scale T. It is found that the diffusion coefficient increases with L and decreases as the energy of the particle is increased. The pitch angle diffusion coefficient is also calculated. The lifetime of slot electrons calculated from the pitch angle diffusion coefficient agrees with the measured values.
