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.
