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 β 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. [ABSTRACT FROM AUTHOR]

The experiment was performed at CCB IFJ PAN in Kraków with the use of the BINA detector. The experimental program and data analysis of proton-induced deuteron breakup reaction at 108 MeV are presented. [ABSTRACT FROM AUTHOR]

The experiment was carried out using BINA detector at KVI in Groningen. For the first time, an extensive analysis of the data collected in back part of the detector is presented, where a clusterization method is utilized for angular and energy information. We also present differential cross sections for the (dd → dpn) breakup reaction within dp quasi-free scattering limit and their comparison with first calculations based on Single Scattering Approximation (SSA) approach.

Experiments devoted to study subtle ingredients of nuclear dynamics were carried out at KVI in Groningen with the use of the ¹H(d, pp)n breakup reaction at the deuteron beam energy of 80 MeV/nucleon. The aim of the work is to determine the breakup cross sections and confront them with the set of modern calculations which model forces acting between nucleons. Elastic scattering process was also measured for the purpose of the cross section normalization. This paper presents preliminary results of the data analysis including geometry cross check, energy calibration, particles identification and sample distributions of the unnormalized breakup cross sections.

Both components of the transverse electron polarization have been measured in free neutron decay. The T-odd, P-odd correlation coefficient associated with polarization component perpendicular to the neutron polarization and electron momentum, was found to be R = 0:006 ± 0:012 ± 0:005. This value is consistent with time reversal invariance, and significantly improves limits on the relative strength of imaginary scalar couplings in the weak interaction. The value obtained for the T-even, P-even correlation coefficient connected with the second transversal polarization component, N = 0:065 ± 0:012 ± 0:004, agrees with the Standard Model expectation providing an important sensitivity test of the experimental setup.

High-precision vector and tensor breakup analyzing powers for the reaction ¹H(dd⃗, pp)n at 130 MeV were evaluated for a large phase space region. Results are compared with rigorous theoretical calculations based on realtic nucleon--nucleon potentials as well as on chiral perturbation theory approach. Theoretical predictions generally describe data quite well, only in a few cases influence of three-nucleon forces is significant. [ABSTRACT FROM AUTHOR]
