Cosmic ray spallation/fusion reactions may yield astrophysically interesting amounts of lithium, beryllium and boron during the early evolution of the galaxy. Title: cosmic-ray nucleosynthesis and the infall rate of extragalactic matter in the solar neighborhood: authors: reeves, h meyer, j-p affiliation. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons , primarily protons and neutrons cosmic ray spallation. We present also some results on cosmic ray spallation production of li cosmic ray nucleosynthesis in the early galaxy with accounting for astration and accretion.
