Elemental and isotopic composition measurements of galactic cosmic rays
Measurements of the relative abundances of elements and their isotopes in galactic cosmic rays, which include both stable and long lived radioactive species, have led to a variety of insights into the nature of the cosmic ray source, the mechanisms involved in accelerating particles to high energies, and characteristics of their transport in the Galaxy. Some key developments that have contributed to the present understanding of cosmic rays are summarized.
