Abstract: | A measurement of absolute differential cross sections of the3He(d,3Hp)p reaction atE
d=23.083 MeV shows the importance of the quasi-free reaction (QFR) mechanism. The observation of a prominent QFR peak indicates that complicated multiple-scattering processes may not be so important as to prevent a simple phenomenological analysis based on two-body interactions. In this respect we isolate final-state-interaction (FSI) effects related toS andP wave3H-p interactions. In particular, the FSI, associated with the4He level at 25.5 MeV of excitation energy, plays a dominant role. |
