We have measured the differential cross-section and the analyzing power (polarization) for p-/sup 4/He elastic scattering at incident kinetic energies of 0.56, 0.80, 1.03, 1.24, and 1.73 GeV. The experiment used a polarized proton beam incident on a liquid helium target and a single arm magnetic spectrometer to detect elastic scattering. Both the differential cross sections and the analyzing power show structure near - t = 0.25 (GeV/c)/sup 2/ which decreases in magnitude with increasing energy. Both multiple scattering and optical model interpretations of the data are discussed.
