• The Scattering of protons by helium has been investigated from 9.2MeV to 14.5MeV with the INSJ variable-energy 160cm cyclotron. The full angular distribution curves were taken at 12.04MeV and 14.32MeV. Both curves have a minimum at 115° and show the evidence of Coulomb-nuclear interference, though very small, at near 18° in the center-of-mass system. Tentative phase shift analysis has been made. It was found that the D-wave phase shifts are closely related with the shape of angular distribution at forward angles and they are small but cannot be neglected. Excitation curves between 9.2MeV and 14.5MeV were also taken at four angles of 25°31', 49°21', 90°0' and 168°41' in the center-of-mass system. lc^2σ(θ) versus energy curve increase gradually with proton energy. They display no new state in Li^5 except the 1/2^- first excited state. The differential cross sections at energies near 9.5MeV have served to resolve the confliction between the values hitherto obtained.
