Abstract
The pp analyzing power was measured using the SATURNE II polarized proton beam and the Saclay frozen spin polarized target. The measurements at 0.88 and 1.1 GeV were carried out in the angular region θCM from 28° to ≅50° and complete our previous measurements from 45 ° to 90°. Above 1.1 GeV the measurements presented here cover both regions, extending from θCM = 28° (at the lower energies) or θCM = 18° (at the higher energies) to θCM > 90°. The shape of the angular distribution Aoono(pp) = ƒ(θCM) changes considerably with increasing energy. The new data show the onset of a characteristic t-dependence of the analyzing power, with a minimum at −t ≅ 1.0 (GeV/c)2 followed by a second maximum at −t ≅ 1.5 (GeV/c)2. This structure is present at all energies, from kinematic threshold to 200 GeV.
