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 $>$30 MeV/nucl); and only 10$^{49}$ 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.

Prediction of lithium isotope fluxes using data-driven production cross sections
astro-ph.HE 2025-02 conditional novelty 5.0 of 10

Adding heavy-progenitor lithium production with cross sections renormalized to measurements removes the AMS-02 lithium excess and predicts 6Li and 7Li fluxes consistent with preliminary data.
