| Outline of Final Research Achievements |
We constructed a reliable microscopic reaction model for describing nucleon and 3,4He elastic scattering simultaneously. The model is “double folding (DF) model with target-density approximation”. The chiral G matrix was constructed from chiral two-nucleon and three-nucleon forces by using Brueckner Hartree-Fock theory. The DF model with the chiral G matrix as an effective nucleon-nucleon force well describes nucleon and 3,4He elastic scattering. The effects of chiral three-nucleon force are large for 3,4He elastic scattering but small for nucleon scattering. Radii of Mg isotopes were determined from measured reaction cross section by using the DF model. 37Mg was found to be a deformed halo nucleus. We proposed a measurable parameter quantifying the halo nature of one-neutron halo nuclei. We determined the upper limit of the strength of the vector-type four-quark interaction for the quark phase to emerge in the inner core of two solar-mass neutron stars.
