Abstract

We have studied the low-energy

{}^{2}H

(d,γ

)^{4}

He 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

{}^{4}{He}

ground state of ≊5–7 %.
