Reactions in three-nucleon systems at intermediate energies, between 50 and 200 MeV/nucleon, attract attention due to theoretically predicted sensitivity of the observables to subtle effects of the dynamics beyond the pairwise nucleon-nucleon force, so-called three nucleon force (3NF). Precise measurements in the sector of elastic nucleon-deuteron scattering show importance of 3NF for...

Polarization observables in the proton-deuteron break-up reaction are sensitive probes to investigate the spin structure of the nucleon-nucleon and three-nucleon forces. A measurement of the analyzing powers for the 2H (p,pp)n break-up reaction was carried out at KVI exploiting a polarized-proton beam produced in an atomic-beam type polarized ion source [1] at a proton-beam energy of 135 MeV....

The dynamics of the three-nucleon system can be very extensively tested
by means of the deuteron-proton breakup reaction. Experimental studies
of the dp system exposes various dynamical ingredients, like three-nucleon force (3NF) and Coulomb force, which play an important role in correct description of observables (e.g. cross section). It is worth to underline that experiments with polarized...

We present measurements of differential cross sections and analyzing powers for the elastic
2H(~d, d)d scattering process. The data were obtained using a 130 MeV polarized deuteron beam
impinging a liquid-deuterium target. The experiments were conducted at the AGOR facility at KVI
using the BINA 4π-detection system. Our measurements are compared to results of previous studies
and with...

Research in the domain of few-nucleon systems is the basis for understanding of nuclear interactions and properties of nuclei.
The precision theoretical calculations for three nucleon systems should be confronted with a rich set of systematic experimental data. For this purpose a series of measurements of deuteron breakup in collision with proton was conducted in KVI Groningen and FZ-Jülich....

Comparison of theoretical predictions based on a nucleon-nucleon potential with data for elastic nucleon-deuteron (Nd) scattering and nucleon
induced deuteron breakup reveals the importance of a three-nucleon
force (3NF). Inclusion of semi-phenomenological 3NF models, such as Tucson-Melbourne or Urbana IX, into calculations in many cases improves the data description. However, some serious...

The probability densities for the ground states of 3H, 3,4,6He, 9Be nuclei were calculated in Refs. [1, 2] by Feynman’s continual integrals method in imaginary (Euclidean) time [3, 4]. The present work is devoted to studying other light nuclei 6,7,9,11Li, 6,10Be using the same approach. For example, the probability density for the 6Li nucleus is shown in Figure. The correctness of calculations...

Even though the development of the theories providing a precise description of few-nucleon interactions is well advanced, certain inconsistencies between experimental data and theoretical predictions are still to be resolved. One of the most intriguing discrepancies observed in the proton-deuteron breakup reaction is known as the Space Star Anomaly [1]. It concerns a very special geometrical...

A detailed description of nuclear forces is essential for understanding the properties of nuclei and the dynamics in few-nucleon scattering processes. The need for an additional three-nucleon potential became evident when comparing three-body scattering observables and light-nuclei binding energies with state-of-the-art calculations[1].
In this work, the analyzing powers (Ax and Ay) and...

Events of dissociation of relativistic nuclei in nuclear track emulsion (NTE) allow a holistic investigation of “cold” ensembles of lightest nuclei. So far, with regard to fine structure dissociation of relativistic nuclei, the NTE technique remains the only means providing unique completeness of such observations at the best angular resolution and as well as a sufficient statistical...
