Experimental studies of few-nucleon systems

Understanding nuclear interactions is the basis for describing nuclear systems, their structure and reactions. Studies of reactions in the simplest systems consisting of a few nucleons provide stringent tests for nuclear interaction models. The data collected by our group over the last 30 years are crucial for understanding the few-nucleon system dynamics. Measurements of observables (cross-section, vector andmtensor analyzing powers) for the deuteron breakup in collision with a proton/deuteron were conducted at SIN/PSI (Switzerland), KVI (the Netherlands), FZ-Jülich (Germany) and CCB IFJ PAN Kraków (Poland), and provided data covering a wide range of the reaction phase-space. Main conclusions following from our research and its current status are presented.
