Cross sections (mb) for the production of Li, Be and B by spallation of CNO nuclei with protons and alphas, as a function of particle energy per nucleon. Data are from Read & Viola (1984) and Mercer et al. (2001, α + α reactions). In all panels thick dotted curves correspond to production of 11B, thin dotted to 10B, thick solid to 7Li, thin solid to 6Li and dashed to 9Be. In the bottom right panel appear the adopted GCR spectra (arbitrary units): injection Q (dotted) and equilibrium F (solid).
