Abstract

We report measurements of the cross-section and a complete set of polarization transfer coefficients for the 3He(p,n) reaction at a bombarding energy Tp=346 MeV and a reaction angle θlab=0°. The data are compared with the corresponding free nucleon-nucleon values on the basis of the predominance of quasielastic scattering processes. Significant discrepancies have been observed in the polarization transfer DLL(0°), which are presumably the result of the three-proton T=3/2 resonance. The spin-parity of the resonance is estimated to be 1/2-, and the distribution is consistent with previous results obtained for the same reaction at Tp=48.8 MeV.
