Light Elements and Cosmic Rays in the Early Galaxy
R. Ramaty, B. Kozlovsky, R. E. Lingenfelter
Abstract
We derive constraints on the cosmic rays responsible for the Be and part of the B observed in stars formed in the early Galaxy: the cosmic rays cannot be accelerated from the ISM; their energy spectrum must be relatively hard (the bulk of the nuclear reactions should occur at >30 MeV/nucl); and only 1049 erg/SNII in high metallicity, accelerated particle kinetic energy could suffice to produce the Be and B. The reverse SNII shock could accelerate the particles.
