Neutron Halo and Nuclear Shell Structure in New Nuclide 31Ne**The project supported by the Foundation of National Educational Commission of China and National Natural Science Foundation of China, and by the Major State Basic Research Development Program under Contract No. G2000774

Abstract

The ground state properties of new nuclide 31Ne are investigated within the framework of the density-dependent relativistic mean-field theory. One-neutron halo in 31Ne is predicted. Calculations also show that the ground state of 31Ne is (3/2)- and it can be used for the testing of the nuclear shell structure near the neutron-drip line.
