- Abstract
- The recent WMAP results tightly constrain the baryon density in the universe, which in turn constrains the light element abundance predicted in Standard Big Bang Nucleosynthesis (SBBN). There is a discrepance in the Li-7 abundance which cannot be explained by uncertainties in the main reactions included in the SBBN. Up to now, the influence of the reaction Be-7(d,p)2 alpha has been neglected. We have investigated this reaction at SBBN energies using a radioactive Be-7 beam and a (CD2)(n) self-supporting target at the CYCLONE RIB facility at Louvain-la-Neuve. The experimental method is briefly described. Preliminary results and consequences for primordial nucleosynthesis are discussed.
