Studies of the three-nucleon system dynamics in the deuteron-proton breakup reaction

One of the most important goals of modern nuclear physics is to construct nuclear force model which properly describes the experimental data. To develop and test predictions of current models the breakup ¹H(d,pp)n reaction was investigated experimentally at 100 and 130 MeV deuteron beam energies. Rich set of data for cross section, vector and tensor analyzing powers was obtained with the use of the SALAD and BINA detectors at KVI and Germanium Wall setup at FZ-Juelich. Results are compared with var- ious theoretical approaches which describe the 3-nucleon (3N) system dynamics. For correct description of the cross section data both, 3-nucleon force (3NF) and Coulomb force, have to be included into calculations and influence of those ingredients is seizable at specific parts of the phase space. In case of the vector analyzing powers very low sensitivity to any effects beyond nucleon-nucleon interaction was found. At 130 MeV, the A_xy tensor data are not correctly described when 3NF models are included into calculations. (authors)
