Abstract. A polarized proton beam extracted from SATURNE II and the Saclay polarized proton target were used to determine the spin correlation parameter $A_{oosk}$ 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 oriented perpendicular to the beam direction in the horizontal scattering plane and the target polarization was directed either along the vertical axis or longitudinally. Left-right and up-down asymmetries in the second scattering were measured. A check for the beam optimization with the beam and target polarizations oriented vertically provided other 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 fixed angles in the vicinity of this energy.
