Three-nucleon interaction dynamics studied via the deuteron-proton breakup

Rich sets of high precision cross sections, vector and tensor analyzing powers for the $^1 H(\vec d,pp)n$ breakup reaction were measured at 130 and 100 MeV beam energy with the use of detection systems covering large parts of the phase space. The cross section data allowed to establish evidences for three-nucleon force contributions and to confirm predictions of sizable effect of the Coulomb force in the breakup reaction. Analyzing power data are generally quite well described by theoretical predictions even with pure nucleon-nucleon interactions. However, in some regions discrepancies has been observed for tensor analyzing powers at 130 MeV.
