Abstract

We performed the experiment of p–$^{3}$He scattering at 65 MeV by using polarized proton beams and the newly constructed polarized $^{3}$He target. The proton analyzing power $A_{y}$, the 3He analyzing power $A^{T}_{y}$, and the spin correlation coefficient $C_{yy}$ were measured. In the conference, the experimental data were compared with the rigorous numerical calculations based on various nuclear potentials. Large discrepancies between the experimental data and the calculations were found in the $A^{T}_{y}$ and the $C_{yy}$ at the backward angles.
