Abstract: | An analysis of fluences of solar cosmic rays (SCRs), measured by the ACE (ULEIS, SIS) and GOES satellites for 1998–2006 over
the wide energy range of 0.05 to 500 MeV/nucleon, is performed. It is shown that the energy spectra of the fluences have two
sections described by power functions of the energy per nucleon: a hard spectrum at low energies (E < 1–10 MeV/nucleon) and a soft spectrum at high energies (E > 10–30 MeV/nucleon). The main regularities inherent to the parameters of the spectra of different particles are determined. |
