Evidence for transfer followed by breakup in 7Li + 65Cu

The observation of a large cross-section for the α+d channel compared to breakup into the α+t channel from an exclusive measurement for the 7Li + 65Cu system at 25 MeV is presented. A detailed analysis of the angular distribution using coupled channels Born approximation calculations has provided clear evidence that the observed α+d events arise from a two step process, i.e., direct transfer to the 2.186 MeV (3+) resonance in the α+d continuum of 6Li followed by breakup, and are not due to final state interaction effects.
