Immediate Consequences of Galactic Cosmic Ray Observations
Summarizing the observational material on galactic cosmic rays presented in the last three chapters we note that the solar system is bombarded by cosmic rays from all sides isotropically. The chemical and isotopic composition of the nucleonic component is similar to that of solar flare particles; all nucleons exhibit power law energy spectra over a wide range of kinetic energies. Cosmic ray electrons exhibit a break in their power law energy spectrum at about 20 GeV with spectral index ≃ 2.2 below the break energy and ≃ 3.2 above the break energy.
