Scientific paper

We have studied the low-energy 2H(d,γ) 4He reaction based on a microscopic description of the nuclear wave functions. Our study reproduces the experimental reaction cross sections at E<=3 MeV; it allows for an extrapolation of the data to energies relevant for big-bang nucleosynthesis resulting in a cross section about 35 times higher than given in present compilations. Our results indicate a D-state admixture in the 4He ground state of ~=5-7 %.
