Abstract
The dependence of the particle energy spectra on the acceleration and loss rates is studied based on the analytical solutions to the equation for the particle distribution function, taking into account diffusion in the momentum space (stochastic acceleration) and loss (due to particle escape from the acceleration region). The energy spectra and time dynamics of the MeV electron fluxes, observed based on the geostationary satellite data during the prolonged recovery phases of the known magnetic storms of June 11, 1980 and November 3–4, 1993, have been analytically described. The acceleration and loss rates have been estimated for these storms. A comparison is performed with the preciously studied energy spectra of MeV electrons and with the acceleration and loss rates during the recovery phases of the magnetic storms of January 10, 1997, and April 6, 2000.
