Abstract

We measured the cross section and the proton analyzing power Ay for p–3He elastic scattering at the angles θ = 26.9◦–170.1◦ in the center of mass system with a 65 MeV polarized proton beam. We compared the data with the rigorous numerical calculations based on the various nucleon–nucleon potentials. For the cross section, clear discrepancy is seen at the angles where the cross section takes minimum. For the proton analyzing power Ay, the calculations have moderate agreements to the data. In this proceedings, we show only the experimental results.
