Precise measurements, in proton-He elastic scattering near 65 MeV, of cross sections, proton and He analyzing powers, and the spin correlation coefficient are compared with rigorous neutron-H scattering calculations based upon realistic two-nucleon potentials. Proton-He scattering at intermediate energies is found to be an excellent tool with which to test nuclear interaction models. Moreover, outstanding features that differ from those seen in nucleon-H elastic scattering suggest the possibility of exploring three-nucleon forces, which are not accessible in three-nucleon scattering.
