Cross sections and analyzing powers A y in the breakup reaction 2 H ( p → , p p ) n at 65 MeV: Star configurations

Cross-section and vector-analyzing-power data for three star configurations of the ${}^{2}\mathrm{H}(p\ensuremath{\rightarrow},pp)n$ breakup reaction at ${E}_{p}^{\mathrm{lab}}=65$ MeV were measured in a kinematically complete experiment. They are compared to rigorous Faddeev calculations involving five realistic charge-dependent nucleon-nucleon potentials: Argonne ${v}_{18},$ CD Bonn, Nijmegen 93, Nijmegen I, and Nijmegen II. A general satisfactory agreement between theory and experiment has been found. However, there exist also a few minor discrepancies in cross sections in some regions of phase space. The experimental data are compared also to the calculations including the (\ensuremath{\pi}-\ensuremath{\pi}) Tucson-Melbourne three-body force. Their effects are either negligible or increase the disagreement with the experiment.
