Proton-helium elastic scattering: a possible high-energy polarimeter at RHIC-BNL
Abstract We examine a suggestion to use p- 4 He elastic scattering, as an absolute polarimeter for high-energy polarized proton beams, by means of a Coulomb-Nuclear Interference effect for the single-spin asymmetry A N ( t ), around the diffractive minimum of the differential cross section |t|∼0.21 GeV 2 . Although this reaction has a fairly simple dynamical structure, our theoretical uncertainties and the present experimental inaccuracy of the differential cross section in this t region, allows one to generate dramatic effects for A N ( t ), which will be discussed.
Proton-4He elastic scattering in the Chou-Yang model
Abstract Proton- 4 He elastic scattering at 400 GeV incident energy provides us with an interesting possibility of testing the Chou-Yang model in the case of a nuclear target. An excellent fit to the experimental data is obtained up to the first diffraction minimum. The situation at ISR energies is briefly discussed.
