Cross sections for the [sup 8]Li([ital d],[ital n])[sup 9]Be (ground state) and [sup 8]Li([ital d],[ital t])[sup 7]Li 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 [sup 9]Be. The cross section for the latter reaction, however, is found to be large enough to destroy significant quantities of [sup 8]Li, and thus could affect predictions of primordial nucleosynthesis yields.
