Resum
The observed primordial Li-7 abundance in metal-poor halo stars is found to be lower than its Big-Bang nucleosynthesis (BBN) calculated value by a factor of approximately three. Some recent works suggested the possibility that this discrepancy originates from missing resonant reactions which would destroy Be-7, parent of Li-7. The most promising candidate resonances which were found include a possibly missed 1(-) or 2(-) narrow state around 15 MeV in the compound nucleus C-10 formed by Be-7+He-3...
