Elastic proton scattering onHe4at 156 MeV

Abstract
The differential cross section for the proton He4 elastic scattering at 156 MeV was measured in the angular range from 10° to 168°. An optical potential analysis with an exchange term is performed and extended to the 100 and 85 MeV data. Some of the impulse approximations are tested and a comparison is performed with a Glauber calculation.
