Abstract
The anomalous component of cosmic rays (ACR) in the heliosphere (Fig. 5.1) was discovered in the early 1970s from spacecraft measurements. The ACR contains light hydrogen ions 1H, as well as heavier ions 4He, C, N, O, Ne, Ar and, possibly, S, Si, and Fe with energies up to ~50 MeV/nucleon, which are found in interplanetary space and in the Earth’s magnetosphere. The chemical composition of this component differs from the solar and galactic content of elements, for example, sometimes there is a certain excess in the content of carbon C in relation to oxygen O.
All things are difficult before they are easy/are done.
