Abstract

The capture of $α$ particles by deuterium has been observed by using a magnetic analysis technique to detect the recoiling ${}^{6}{Li}$ ions. Measurements of the cross section down to 1 MeV in the center-of-mass system can be interpreted accurately in terms of a direct-capture model, and it is found that production of ${}^{6}{Li}$ in the big bang is 5 times smaller than has been assumed.
