- Abstract
- An analysis of the dependence of the amplitudes of the 10 strongest preceded by Halo-type CMEs Forbush decreases in proton and helium nuclei fluxes according to AMS-02 data on the magnetic rigidity of particles showed that it is well approximated by a power function (as was shown in the PAMELA experiment) in the rigidity range from 1 to 10–12 GV. The index of this function is in the range from –0.38±0.02 to –0.68 ± 0.04 for protons and from –0.41± 0.03 to –0.79 ± 0.04 for helium nuclei. But in a wider range of rigidity values up to 20 GV, such approximation significance level is only 90–92% for protons and 90–96% for helium nuclei. Exponential functions providing 95–99% significance level both for protons and helium nuclei should be used over the entire range of rigidities. Comparison of time series for protons according to AMS-02 and GOES-15 data shows the possibility of observing SEP and SPE together with the background Forbush decreases.
