Description

The dynamics of the three-nucleon system can be extensively studied in the deuteron-proton (dp) system. Experimental investigations of the deuteron breakup in dp scattering allow for observing the effects of various dynamical components, such as the three-nucleon force (3NF) and the Coulomb force. Measurements of cross sections as well as polarization observables (e.g. vector and tensor analyzing powers [1]) enable rigorous testing of theoretical calculations based on various approaches [2–5] for modeling interactions in three-nucleon systems.
Additionally, studies of the $^1$H(d, pp)n reaction at low energies (e.g. 50 MeV/nucleon) are crucial for testing predictions of Chiral Effective Field Theory (ChEFT) [6].
The presentation will focus on the effects of the 3NF and the Coulomb force in the differential cross section for the dp breakup reaction, studied over a wide range of energies from 50 and 190 MeV/nucleon [8–11]. Moreover, our data will be presented in the invariant coordinate regime. The data collected at 50 MeV/nucleon will be compared with predictions from ChEFT [7].
Furthermore, information about ongoing and planned projects conducted at the Cyclotron Center Bronowice, PAS, Kraków, Poland, will also be discussed.
