Abstract
High-quality vector analyzing power data for the 1 H(d,pp)n breakup reaction and elastic scattering at 100MeV beam energy have been measured in a large part of the phase space for these processes. The results are compared to theoretical predictions obtained using the charge-dependent Bonn potential alone or combined with the three-nucleon force TM99 as well as to the results of calculations in the coupled-channel approach, with or without the inclusion of the Coulomb interaction. In the studied observables, effects of the 3NF and the Coulomb force are almost absent. The pairwise NN interactions alone are sufficient to describe the experimental results.
Highlights
A first indication of the significance of 3NF contributions came from the 3H and 3He bound state studies [10]
Vector analyzing powers Ax(ξ) and Ay(ξ) for the d-p breakup reaction at 100 MeV have been obtained as a function of S (MeV) for geometries defined by the emission angles of the outgoing protons
A large set of experimental data for the vector analyzing powers has been obtained for deuteron-proton collisions at the deuteron beam energy of 100 MeV
Summary
A first indication of the significance of 3NF contributions came from the 3H and 3He bound state studies [10]. The data base for the elastic nucleondeuteron scattering has been recently enriched by a large number of precise experiments performed in various laboratories [13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]. The results of those studies confirm the importance of 3NFs for describing the elastic scattering. The emerging picture is rather complex, especially in the sector of polarization observables
