Pairing correlations in nuclei on the neutron-drip line
K. Hagino, H. Sagawa
Abstract
Paring correlations in weakly bound nuclei on the edge of neutron drip line is studied by using a three-body model. A density-dependent contact interaction is employed to calculate the ground state of halo nuclei 6He and 11Li, as well as a skin nucleus 24O. Dipole excitations in these nuclei are also studied within the same model. We point out that the di-neutron type correlation plays a dominant role in the halo nuclei 6He and 11Li having the coupled spin of the two neutrons S=0, while the correlation similar to the BCS type is important in 24O. Contributions of the spin S=1 and S=0 configurations are separately discussed in the low energy dipole excitations.
