Abstract
The ground state properties of eveneven O, Ne, Mg, Si, S, Ar, Ca and Ni isotopes were studied with the selfconsistent deformed relativistic mean field theory with NL3 parameter set. The calculated results of O and Mg isotopes were presented in detail. The calculated binding energies and the twoneutron separation energies were in good agreement with experimental values. By examining the twoneutron separation energies, it was suggested that 30O, 38Ne, 42Mg, 52Si, 54S, 60Ar, 80Ca and 98Ni are the twoneutron drip line nuclei. We also briefly discussed the possible changes of neutron magic numbers in Ca and Ni isotopes. Key words: relativistic mean field; drip line nucleus; twoneutron separation energy
