Abstract : Probabilities for injecting protons into the radiation belts for large regions of B-L space by cosmic ray albedo neutron decay, CRAND, and by solar proton albedo neutron decay, SPAND, are computed. A 7094 computer program simulates the ejection of neutrons from the atmosphere of the earth. The computations are compared with both directional and omnidirectional experimental data. The trapped proton flux from SPAND injection is evaluated using the currently estimated solar proton flux and found to be small compared to CRAND injection. Below 20 MeV, in many regions of space, there are too many protons to be accounted for by either CRAND or SPAND injection, and some other source is required. (Author)
