摘要：
The properties of N = 41 isotones are investigated systemically by using the nonlinear relativistic mean field theory. It is found that all the calculating binding energies with four different interactions are comparable for the ground and low-lying excited states, and very close to the data available. The calculations show that there exists a neutron halo in the first excited state in Ni-69, as well as in the second excited state in 69Ni. It is also predicted that there exists a neutron halo in the first excited state in Cr-65, Mn-66, Fe-67 and Co-68.
