ANGULAR-DEPENDENCE OF PP SPIN CORRELATION AND RESCATTERING OBSERVABLES BETWEEN 1.80 AND 2.10 GEV

A polarized proton beam extracted from SATURNE II and the Saclay polar ized proton target were used to determine the spin correlation paramet er A(oosk) and the rescattering observables K-os '' so, D-os '' ok, N- os '' sn, and N-onsk at 1.80 and 2.10 GeV. The beam polarization was o riented perpendicular to the beam direction in the horizontal scatteri ng plane and the target polarization was directed either along the ver tical axis or longitudinally. Left-right and up-down asymmetries in th e second scattering were measured. A check for the beam optimization w ith the beam and target polarizations oriented vertically provided oth er observables, of which results for D-onon and K-onno at 1.80, 1.85, 2.04, and 2.10 GeV are listed here. The new data at 2.10 GeV suggest a smooth energy dependence of spin triplet scattering amplitudes at fix ed angles in the vicinity of this energy.
