Measurement of the angular distribution of 4He(p, d)3He, 4He(p, 3He)pn and 4He(p, t)pp reactions

Abstract We have measured the angular distribution of the reaction 4 He(p, d) 3 He at 47 MeV over the center-of-mass angular range of 12–166°. We have also measured the angular distributions of the reactions 4 He(p, 3 He)pn and 4 He(p, t)pp in the region of the nucleon-nucleon final state interaction at the same bombarding energy over an angular range of 7.5° to 50.0° in the laboratory. The 3 He and triton energy spectra are also presented and Watson-Migdal fits to these data in the region of the nucleon-nucleon final state interaction are shown.
