Description:
In the light of recent research results, the composition of low-, medium-, and high-energy cosmic ray charges is reviewed, and its energy dependence is examined. Cosmic ray antinuclei research is summarized, and it is shown that no positive identification of primary antimatter has so far been achieved. Special attention is given to the relative abundances of cosmic ray charges at the source, and the difficulties encountered in the extrapolation of experimental abundances back to the source are reviewed, along with some of the attempts made to circumvent these difficulties. Recent discussions and the present status of hypotheses on modification of the source composition by injection and acceleration processes are also reviewed.
