Production of nuclei on the sun
Abstract
Satellite and rocket observations of multicharged nuclei produced during solar cosmic-ray flares are reviewed. Cases where preferential acceleration of heavy nuclei was detected are discussed, typical increases in fluxes of nuclei with charges of two and greater are analyzed, and preliminary satellite data are presented on increases in the nuclear component of cosmic rays associated with the production of nuclei on the sun. It is shown that: (1) the energy spectrum of protons produced during a solar flare is much softer than the quiet-time spectrum; (2) two acceleration mechanisms operated during a particular solar flare, one of which assured the preferential acceleration of multicharged nuclei: (3) certain solar processes produce cosmic rays in correspondence with the chemical-element abundance in the solar atmosphere; and (4) certain other processes produce mainly heavy nuclei, with the result that increases in the multicharged component of cosmic rays are observed.
