Abstract
A series of experiments studying deuteron breakup in collision with proton was performed with the use of large acceptance detectors: SALAD and BINA at KVI Groningen and CCB PAS Krakow, GeWall and WASA at FZ-Juelich. Differential cross section and, in some cases, vector and tensor analyzing powers were measured over a significant part of the reaction phase space and a wide range of beam energies, from 50 to 200 MeV/nucleon. The collected data provided a~basis for systematic comparison with the state-of-the-art theoretical calculations, demonstrating the importance of the three-nucleon force (3NF), and sensitivity of the breakup cross section to Coulomb interaction in the final state. There are many challenges in describing polarization observables and introducing 3NF does not necessarily resolve these discrepancies.
A brief survey of the results is given, with emphasis on the energy dependence of particular effects or problems in description of the experimental data. Moreover, the prospectives of further studies of few-nucleon systems using BINA at CCB PAS Krakow are discussed.
