Investigation of the NN interaction from polarization transfer experiments in low energy pp scattering

Abstract

The polarization-Transfer observables Kyy1(θ), Kxx1(θ) and Kzx1(θ) for proton-proton scattering have been measured at Ep = 25.68MeV. A simultaneous phase-shift analysis of these new data with differential cross section and analyzing power data at the same energy resulted in a very accurate determination of the p-wave phase-shift combinations ΔC, ΔLS and ΔT and of the 3F2−3P2 mixing parameter ϵ2. With this complete set of high precision data a critical test of microscopic NN-potential models has been performed.
