Differential Cross Section for Proton Induced Deuteron Breakup at 108 MeV

The differential cross sections for the proton-deuteron breakup reaction have been measured for more than 200 angular configurations of outgoing protons in the range of polar angles from 13 to 27 degrees with a proton beam at 108 MeV. The paper presents the experimental results of the selected configurations, which are compared to state-of-the-art theoretical calculations. In some regions of the phase space, a strong influence of the Coulomb interaction is observed.</p

The forward-plane star in 1H(d, pp)n breakup at Edd=80 MeV/nucleon

Analysis of the data acquired with the BINA detector system in 1H(d, pp)n reaction at the beam energy of 80 MeV/nucleon makes a systematic analysis of the star configurations possible. This paper shows the preliminary cross section of the Forward-Plane Star (FPS) configuration with the neighbouring configurations

Simulation of Star configurations in the BINA detector

Star Anomaly is one of the most intriguing and unsolved discrepancies between theoretical calculations and experimental data observed in the domain of few-nucleon systems at low energies. Previous and upcoming measurements of the breakup reaction with the use of the BINA detector enable systematic studies of the Star configurations at intermediate energies. A dedicated simulation was developed to study feasibility of registering such events with the required accuracy and to support the future data analysis. An additional rotation angle has been introduced to parametrise the Star configurations. First results concerning the acceptance of certain segments of BINA for registering the Star configurations are presented

Experimental studies of few-nucleon systems

Special issue, XLVI Extraordinary Congress of Polish Physicists, Warsaw, Poland, October 16–18, 2020Understanding nuclear interactions is the basis for describing nuclear systems, their structure and reac-tions. 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 un-derstanding the few-nucleon system dynamics. Measurements of observables (cross-section, vector and tensor 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 fol-lowing from our research and its current status are presented
