The possibility that big‐bang nucleosynthesis (BBN) may produce nontrivial amounts of 6Li is under study since the recent observations of this element in old halo stars. However, the interpretation of these observations needs a precise knowledge of the reaction rate of D(α, γ)6Li which, at present, is extremely uncertain (a factor of 20) at the energies of astrophysical interest (E cm ⩽ 300 keV). This uncertainty originates from difficulties in both theoretical estimates and experimental determinations of the D(α, γ)6Li capture reaction cross section. New measurements of the cross section of D(α, γ)6Li reaction using Coulomb dissociation of 6Li at 150 A MeV have been performed recently at GSI. The results will be compared to previous measurements and theoretical calculations.
