A model of the primary cosmic ray spectra

We have collected published experimental measurements of the galactic cosmic ray spectra of the primary elements, H, He, C, O, Ne, Mg, Si and Fe in the energy range from 45 MeV/nucleon to 1 TeV/nucleon in the years 1963-1987. We have fit these data with a solution to the spherically symmetric diffusion equation using boundary spectra which are a solution of the cosmic ray propagation equation in the leaky-box model. In this work, we show how the energy spectra of these elements at 1AU are represented by this model. Copyright (C) 1996 Elsevier Science Ltd
