Abstract
The energy, angular, and latitude distributions of energetic neutrons (up to 2 GeV) leaking from the top of the atmosphere have been calculated. The results agree with the recent measurement of Preszler, Simnett, and White, whose leakage rates were well above the calculation of Lingenfelter. Since the spectrum of Lingenfelter has served for evaluating the cosmic-ray albedo-neutron decay (CRAND) source of energetic protons in Earth's inner radiation belt, it is suggested that the results reported here be used to reevaluate the CRAND contribution.Keywords
