Recent observations of 6Li in metal poor stars suggests a huge production of this isotope during BBN, through the 2H(α, γ)6Li reaction. This reaction has never been directly measured inside the BBN energy region because its cross section drops steeply at low energy, while indirect measurements using the Coulomb dissociation of 6Li only give upper limits due to the dominance of nuclear breakup process. Exploiting the ultralow background at the 400 keV LUNA accelerator, located deep underground in Italy’s Gran Sasso laboratory, for the first time the reaction has been measured directly at BBN energy. The LUNA data and their implications for the BBN theory are discussed.
