Research Abstract

Using the nuclear density functional theory, we have studied collective dynamics which emerge in neutron-rich nuclei containing neutrons with small binding energy. We have clarified anomalous behaviors of the pair vibrational mode and associated neutron-pair transfer amplitude. We have developed a continuum quasiparticle random phase approximation designed to describe the direct neutron capture cross section relevant to the r-process nucleosynthesis. We have clarified the microscopic mechanism of the di-neutron correlation in near-drip-line nuclei.
