Outline of Final Research Achievements

In the wide area of the study of nuclear physics, the nuclear forces play a fundamental role. The nuclear forces have only two-body but also many-body interacting components. In this research, we aimed to study directly the effects of the isospin T=3/2 three-nucleon force from the tri-neutron resonant state. For this purpose, we developed the deuterium targets, performed the test of the beam line detectors for the high intensity RI beam, and simulated the simultaneous three-neutron detection by using large acceptance neutron detector NEBULA. Addition to that, we studied the continuum states of the three-nucleon systems at the intermediate states from the analysis of the proton and deuteron scattering reactions.
