Abstract

The 6Li(p, pd)4He reaction was studied at 200.2 MeV, at the quasi-free angle pair (θp, θd) = (54°, −48.9°), for noncoplanarity angles φ from 0° to 28°. 6Li αd spectroscopic factors of 0.84 and 0.76 are deduced from our coplanar data at this energy and 120 MeV, respectively, for ground-state 2S Woods-Saxon wave functions. A recent microscopic three-body calculation predicts spectroscopic factors from 0.70 to 0.75; using the ground-state wave functions from this study, we deduce a factor of 0.76 from the 200 MeV data. DWIA calculations fit the measured integrated cross sections versus φ for spectator momenta Pα ≲ 100 MeV/c at both bombarding energies, but underpredict them for larger Pα. Momentum form factors were better reproduced with 1S αd cluster wave functions for a soft-core bound-state potential than with the 2S Woods-Saxon wave functions, but the former wave functions generate unphysically large (∼1.25) spectroscopic factors.
