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.
