Abstract

The proton-proton interaction has been studied intensively for a long time. At low energies the phase shifts are well determined by phase shift analyses of different groups [refs. 1–3]. However, the precision of the phase shifts for energies around 50 MeV is still not sufficient to distinguish between different model calculations [refs. 3,4]. Therefore, it has been suggested [ref. 5] a long time ago to measure the analyzing power Ay at roughly 50 MeV with a high precision of the order of a few times 10-4 in order to reduce the uncertainties in the 3PT tensor and the spin-orbit 3PLS p-wave parameters. These phase-shifts depend sensitively on the assumptions used in different (theoretical or (semi)-phenomenological) models of the nucleon-nucleon interaction [ref. 6].
