Abstract

For ${}^{6}{Li}$ beam energies of 2 MeV, $α - α$ coincidence measurements show a large, narrow peak due to the direct reaction $2 {}^{6}{Li} \to 3 α$ , where both ${}^{6}{Li}$ nuclei contribute one deuteron to make the third $α$ particle. The large volume of three-body phase space allows the various parts of the reaction process to be separated from each other. Excellent fits to the data were obtained using a three-body, extended-range, distorted-wave Born-approximation model. Elastic scattering potentials for the calculation were generated by the double-folding technique in combination with ${}^{6}{Li}$ + ${}^{6}{Li}$ elastic scattering measurements for ${}^{6}{Li}$ beam energies from 2 to 5.5 MeV.
