Abstract：
The ground state properties of the four isotope chains, ²⁸Ni, ⁵⁴Xe, ⁷⁸Pt, ⁹⁴Pu are studied in the relativistic mean-field theory by using two sets of parameters, NL-3 and NL-Z. We find that the binding energies of odd-A nuclei are even closer to the corresponding experimental results, compared with those of the even-even nuclei. Our results indicate that it is reliable to neglect the space component of the vector meson fields in calculating binding energies of odd-A nuclei in the relativistic mean-field theory.
