Abstract

We have measured the differential cross-section and the analyzing power (polarization) for p-He4 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)2 which decreases in magnitude with increasing energy. Both multiple scattering and optical model interpretations of the data are discussed. NUCLEAR REACTIONS elastic scattering, p-He4; GeV energies; measured differential cross section; measured polarization; comparison with theory.
