Kinetic Energy [ GeV Nucleon

Figure 6.8: Typical differential energy spectra of primary cosmic ray protons and helium nuclei. The solid lines show the average spectra. The modulation effects are illustrated by the dashed lines; the upper lines indicate the intensity during solar minimum and the lower during solar maximum. Note that the proton intensities are multiplied by a factor of 5 to avoid overlapping with the helium spectra. The modulation effects cease at higher energies (after Smart and Shea, 1985).
