Elastic and quasi-elastic pp scattering in $^6$LiH and $^6$LiD targets between 1.1 and 2.4 GeV

Abstract.

A polarized proton beam extracted from SATURNE II, the Saclay polarized target with $^6$Li compounds, and a $\mathrm{CH}_2$ target were used to measure elastic and quasi-elastic pp spin-dependent observables in the angular region $60^{\circ} < \theta_{\mathrm{CM}} < 105^{\circ}$. The beam and/or target polarizations were oriented vertically. Accurate pp data for the analyzing power $A_{\mathrm{oono}}$, spin-correlation parameter $A_{\mathrm{oonn}}$, and the polarization transfer $K_{\mathrm{onno}}$ were measured at 1.1 GeV. The observables $A_{\mathrm{oono}}$ and $K_{\mathrm{onno}}$ were determined at six other energies between 1.6 and 2.4 GeV. At 1.6 GeV, $A_{\mathrm{oonn}}$ was also obtained. The individual contributions from H, $^6$Li, and $^6$LiD were deduced. The $\mathrm{CH}_2$ target provided $A_{\mathrm{oono}}(\mathrm{pp})$ results on free hydrogen and on protons in carbon. The elastic and quasi-elastic observables are compared with existing data and with phase-shift analysis predictions.
