Description

The study of three-nucleon (3N) systems serves as a fundamental testing ground for our understanding of nuclear interactions, bridging the gap between basic nucleon-nucleon (NN) potentials and the complex dynamics of many-body nuclei. Experiments performed at intermediate beam energies reveal that various dynamical ingredients, such as the three-nucleon force (3NF) and Coulomb force, play an important role in accurately describing observables. High-precision measurements of differential cross sections for elastic scattering and breakup reactions, as well as spin observables like vector and tensor analyzing powers enable rigorous testing of theoretical calculations based on various approaches [1–4] to modeling interactions in three-nucleon systems. Additionally, studies of the $^1$H(d, pp)n reaction at relatively low energies are crucial for testing predictions of Chiral Effective Field Theory [5].
The presentation will focus on the effects of the 3NF and the Coulomb force on the differential cross section of the $dp$ breakup reaction, measured over a wide range of energies between 50 and 170 MeV/nucleon [6–10]. Furthermore, information about ongoing projects conducted at the Cyclotron Center Bronowice, PAS, Kraków, Poland, will also be discussed.
