Polarization-Transfer Coefficients in $D(\vec {p},\vec {p})d$ and $D(\vec {p},\vec {d})p$ Reactions at $E_{p} = 19$ MeV: Experiment Compared to Calculations with Recent Nuclear-Interaction Models

Abstract

The polarization-transfer coefficients K\(\), K\(\) and K\(\), K\(\) have been measured in the elastic scattering reactions D(\(\), \(\))p and D(\(\), \(\))d at \(\) MeV, respectively. They are compared to solutions of the three-nucleon Faddeev equations obtained with the recent nucleon-nucleon interactions AV18, CD Bonn, NijmI and II. Effects of the Tucson-Melbourne three-nucleon force, adjusted separately to reproduce the triton binding energy for each of these potentials, are studied. Both \(\) and \(\) exhibit a scaling behaviour with the triton binding energy. For \(\) and \(\) the various predictions with two-nucleon forces only agree practically with each other but spread after inclusion of the three-nucleon force. The agreement of theory and data is fair but the neglect of the proton-proton Coulomb force precludes a final conclusion.
