Abstract
Measurements of [Formula Presented] spin correlation coefficients [Formula Presented] and [Formula Presented] and analyzing power [Formula Presented] for [Formula Presented] elastic scattering at 197.4 MeV over the laboratory angular range 3.5 °–43.5 ° [Formula Presented] have been carried out. The typical statistical accuracy per 1[Formula Presented] angle bin is better than 0.02 for the [Formula Presented] and better than 0.005 for [Formula Presented] Systematic errors are negligible except for an overall normalization uncertainty of 2.5% for [Formula Presented] and 1.3% for [Formula Presented] The experiment makes use of a polarized hydrogen gas target internal to a proton storage ring (IUCF Cooler) and a circulating beam of polarized protons. The target polarization is switched in sign and direction [Formula Presented] every 2 s by reversing a weak guide field [Formula Presented] mT). Scattered and recoil protons are detected in coincidence by two sets of wire chambers, by scintillators, and by silicon-strip recoil detectors placed 5 cm from the proton beam. Analysis methods and comparison to recent [Formula Presented] partial-wave analyses and [Formula Presented] potential models are described.
