Abstract
Three-nucleon system dynamics, determined mainly by pairwise nucleon-nucleon (NN) interaction, can be investigated quantitatively by comparing predictions based on rigorous solutions of the Faddeev equations with results of precise measurements. Proper description of the experimental data can be achieved only if the dynamical models include, in addition to the NN potential, subtle effects of suppressed degrees of freedom, effectively introduced by means of genuine three-nucleon forces. Another dynamical effect which is needed for correct reproducing of the measured observables is the long-time neglected Coulomb force. A large set of high precision, exclusive cross-section data for the 1H(d,pp)n breakup reaction at 130 MeV contributes significantly to constrain the physical assumptions underlying the theoretical interaction models. Comparison of nearly 1800 cross section data points with the predictions using nuclear interactions generated in various ways, allowed to establish importance of including both, the three-nucleon and the Coulomb forces to significantly improve description of the whole data set.
