Abstract
The main objective of this work is to identify anomalies in the energy spectra of cosmic ray nuclei during proton events. Energy spectra of cosmic ray nuclei were obtained from data collected by the GOES and ACE spacecraft between November 11, 1997 to September 13, 2005. The experimental data were approximated by a power function of cosmic ray nuclei rigidity. For this purpose, calculations were performed for the energy spectra of H, C, N, O, Ne, Mg, Si, S and Fe cosmic ray nuclei in the energy range from E = 1 MeV/nucleon to 1000 MeV/nucleon for various events. A new phenomenon was discovered: an intersection and bend in the energy spectrum of cosmic ray nuclei in near-Earth space in the energy range from 8 to 22 MeV/nucleon during proton events. The energies at the intersection point (E p ) of the energy spectra, which correspond to the stability point of the cosmic ray nucleus flux, were determined, which depend on the Z of the nuclei. The mechanism of interaction between cosmic ray fluxes in near-Earth space during proton events is discussed.
