Abstract

High precision vector and tensor analyzing powers for the ¹H(d, pp)n breakup reaction were measured at 130 MeV beam energy with the detection system covering a large part of the phase space. Results are compared with rigorous theoretical calculations based on realistic nucleon-nucleon potentials, also with so-called three-nucleon force included, as well as on chiral perturbation theory. Theoretical predictions generally describe data quite well although in some regions discrepancies have been observed, what indicates incompleteness of the present-day treatment of the three nucleon system dynamics.
