Аннотация:The paper contains the analysis of the energy spectra of solar energetic protons, which differs from the earlier analyses in that not only a broader energy range is analyzed, but also the method of simultaneous statistical analysis of a large data set is used. The SEP events supported by the proton peak flux data in a very broad energy range (METEOR, IMP8, GOES, balloons, and ground-based neutron monitors) are analyzed. The resultant energy range for the analyzed events turns out to extend from 4 MeV to 11 GeV. The statistical analysis has shown that the 30 MeV SEP event proton energy spectra are most adequately described by power-law functions of rigidity
