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 Tpโ = 346 MeV and a reaction angle ฮธlabโ =
0โ.
The data are compared with the corresponding free nucleon-nucleon values on
the basis of the predominance of quasi-elastic scattering processes.
Significant discrepancies have been observed in the polarization transfer
DLLโ(0โ), which are presumably the result of the three-proton T =
3/2 resonance.
The spin--parity of the resonance is estimated to be 1/2โ, and the
distribution is consistent with previous results obtained for the same reaction
at Tpโ = 48.8 MeV.Comment: 4 figures, Accepted for publication in Physical Review
