Abstract
A polarized proton beam extracted from SATURNE II and the Saclay polarized proton target were used to measure the rescattering observables Konno and Donon at 26 energies from 1.94 to 2.80 GeV and at 0.80 GeV. The beam and target polarizations were oriented vertically and left-right as well as up-down asymmetries in the second scattering on carbon were measured. The present data, obtained in small energy steps, are practically constant as a function of energy at $90^{\circ} CM$, where Konno = Donon. These data will bring about important modification to phase shifts and stabilize the solutions.
