Systematic studies of the three-nucleon system dynamics in the deutron-proton breakup reaction

Abstract

Precise and large sets of data for cross section, vector and tensor analyzing powers for the 1H(~d; pp)n breakup reaction were obtained in experiments carried out at KVI Groningen and FZ-Jülich at deuteron beam energies of 100MeV, 13MeV and 160MeV (cross sections only). These precise experimental data obtained in a wide phase-space region allowed to establish evidences for three-nucleon force contributions and to confirm predictions of sizable effect of the Coulomb force. The vector analyzing powers data are generally quite well described by theoretical predictions even with pure nucleon–nucleon interactions. Tensor analyzing powers can be also very well reproduced by calculations in most of the studied region but in some regions locally discrepancies are observed at energy of 130MeV.
