英文摘要 | The neutron-drip-line nucleus N-23 is investigated in a three-body model consisting of a N-21 core and two valence neutrons. Using the Faddeev formalism with the realistic neutron-neutron potential and the neutron-core potential, we calculate the ground-state properties of N-23 including its two-neutron separation energy, and obtain good agreement with the experiments. We also find an excited N-23 state with a shallow two-neutron separation energy at about 0.18 MeV. By evaluating the root-mean-square matter radii, the average distances between the two valence neutrons, and the average distances from the core to the center of mass of the valence-neutron pair, we show that the excited state of N-23 has a distinct halo structure. The large radius and very extended spatial distribution of the weakly bound excited state indicate the evidence of Efimov physics in the drip-line nucleus N-23. |
