Research Abstract
We have conducted two research projects: the study of "multi-neutron clusters" that form semi-hierarchies in nuclear layers, and the investigations of characteristic "forces" specific to nuclei that hold the key to connecting these hierarchies. For multi-neutron clusters, we achieved the first observation of 28O, the observation of a dineutron structure, and completed a detector setup for the production experiment of 10He, where multi-neutron clusters are expected. In the research on "force," we developed a highly polarized, high-density 3He target for measuring spin observables in proton-3He scattering. We measured p-3He elastic scattering with high precision and extracted spin correlation coefficients, which clarified that this reaction can be a powerful probe for Fujita-Miyazawa type and isospin T=3/2 sensitive three-body forces. In addition, we derived spectroscopic factors for orbits with minimal medium effects, demonstrating the high accuracy of the (p,pN) reaction method.
