Abstract

We have measured the asymmetry parameter A and the spin correlation parameter A_nn in pp elastic scattering, using the Argonne ZGS polarized proton beam and a polarized proton target. Angular distributions of A and A_nn for |t| ≳ 0.2 (GeV/c)² were obtained at eight momenta between 1.10 and 2if2.75 GeV/c. We find significant structure in both the energy and t-dependence of A_nn at these energies. At p_lab ≈ 1.34 GeV/c A_nn reaches a very large value of about 0.8–0.9 near θ_cm = 90°.
