Solar cycle modulation of the radiation belt proton flux

摘要: The purpose of this paper is to predict in an exhaustive way the solar cycle time variations be expected trapped radiation belt proton flux on assumption a neutron decay source. By ‘exhaustive’ we mean that, once interested reader decides suitable models for earth's atmosphere and magnetic field (we will recommend some), he should, by reading paper, able protons any energy pitch angle at point space. We have also devoted considerable attention derivation from Boltzmann equation simplified transport commonly used discussing energetic low L values. Emphasis given various approximations involved.
