Experiments of Few-Nucleon Scattering to Explore Three-Nucleon Forces

Few-nucleon scattering offers a good opportunities to study dynamical aspects of three-nucleon forces, that are momentum, spin and isospin dependent. In the paper, the experimental results of deuteron-proton elastic scattering at \(\sim ~\mathrm 100\) $\sim 100$ MeV/nucleon obtained in the course of the study are presented. The experimental study of few-nucleon scattering has been recently extended to the proton- \(^3 \textrm{He}\) ${}^3\text{He}$ scattering with the aim of approaching the isospin \(T=3/2\) $T=3/2$ channel in three-nucleon forces. The data are in comparison with the rigorous numerical calculations based on state-of-the-art nuclear potentials with three-nucleon forces.
