Analyzing Power Measurements of Quasi-Elastic Proton–Proton Scattering at the Intermediate Energies at the Nuclotron Internal Target

Obtaining new data on the polarization observables is the important part of the nucleon–nucleon scattering models’ development. For this purpose, the polarized deuteron beam and the detection setup at the Nuclotron internal target station were used. Counters were mounted in according to $$pp$$ -elastic scattering kinematics. Relevant events were selected using time and amplitude information from the counters. The polyethylene target was used as the main target. Auxiliary carbon target was used to remove the background. This article presents the results of the vector analyzing power measurement for the proton–proton quasi-elastic scattering at the deuteron beam energies of 200, 500, 550, 650 MeV/nucleon. The obtained results are in a good accordance with the data of other experiments and the partial wave analyzis SP07 SAID predictions.
