| Research Abstract |
We have studied the structure of neutron-rich nuclei in medium-mass regions with focus on the expected di-neutron correlation and exotic modes of collective excitation by means of the coordinate-space Hatree-Fock-Bogoliubov mean-field theory and the continuum quasiparticle random-phase approximation. It is found that the two-neutron transfer with the monopole and quadrupole multipolarity is a sensitive probe to the di-neutron correlation at nuclear surface, and also that an anomalous pair vibration emerges in neutron-rich Sn isotopes beyond the N=82 magic number. We have also succeeded in constructing the coordinate-space HFB theory for axially deformed nuclei by using the Green's function technique. Applying this method, we have clarified the pairing properties and the quasiparticle spectra in deformed nuclei near the neutron-drip line.
