2H induced reactions on 8Li and primordial nucleosynthesis
Abstract
Cross sections for the 8Li(d,n)9Be (ground state) and 8Li(d,t)7Li reactions, both important to primordial nucleosynthesis in the inhomogeneous models, have been measured using a radioactive beam technique. The cross section for the former reaction is found to be small, so it is important only for synthesis of 9Be. The cross section for the latter reaction, however, is found to be large enough to destroy significant quantities of 8Li, and thus could affect predictions of primordial nucleosynthesis yields.
