Proton-proton elastic scattering analyzing power in the 2.16 to 2.28 GeV energy region

Abstract

The angular dependence of the pp elastic scattering analyzing power was measured at SATURNE II with an unpolarized proton beam and the Saclay polarized proton target. The energy region in the vicinity of the accelerator depolarizing resonance Gγ = 6 at T kin = 2.202 GeV was studied. Measurements were carried out at seven energies between 2.16 and 2.28 GeV from 17 • to 55 • CM . No significant anomaly was observed in the angular and energy dependence of the results presented, whereas the existing data sets differ in this energy range.

Nucleon-nucleon elastic scattering analysis to 2.5 GeV

“…About 2000 polarized pp measurements are expected above 1000 MeV [74] as the nucleon-nucleon program at SAT-URNE II is completed. While not included in the present fit, preliminary data [75] from SATURNE II is in reasonable agreement with our predictions. A representative fit to P data, at 2.16 GeV, is given in Fig.…”

Nucleon-nucleon elastic scattering to 3 GeV

“…[13] considered this possibility but found no evidence in their differential cross section measurements. No significant anomaly was seen in the angular and energy dependence of detailed analyzing power [10] and correlated spin measurement at Saclay [8].…”
