Abstract

A polarized proton beam from SATURNE II, the Saclay polarized targets with $^6$ Li compounds, and an unpolarized $\mathrm{CH}_2$ target were used to measure spin-dependent observables for protons scattered on bound nucleons. The beam and target polarizations were oriented vertically. The analyzing power $A_{\mathrm{oono}}$ and the depolarization $D_{\mathrm{nono}}$ were determined at seven energies between 1.1 and 2.4 GeV. The spin correlation parameter $A_{\mathrm{oonn}}$ was measured at only 1.1 and 1.6 GeV. Measurements with the $\mathrm{CH}_2$ target at 1.1 GeV provided $A_{\mathrm{oono}}$ data for scattering of polarized protons on neutrons in carbon. The quasi-elastic observables are compared with previous elastic scattering measurements and at 1.1 GeV with predictions of phase shift analyses.
