On stochastic instability of high-energy protons of the inner radiation belt at low altitudes.
Abstract
The present study determines the lifetimes and fluxes of trapped protons with energies exceeding 100 MeV, associated with nonadiabatic motion at low altitudes and geomagnetic latitudes exceeding approximately 35 deg in the region of the Brazilian anomaly. Stochastic instability is the nonadiabatic mechanism which is considered. It is shown that losses caused by stochastic instability exceed atmospheric losses at altitudes exceeding approximately 300 km. Satellite (Cosmos 721 and 137) data on this stochastic instability are examined.
