Ground State Properties of Z = 114 Isotopes in the Relativistic Mean-Field Theory

The ground state properties of even-even Z = 114 nuclei have been investigated in the relativistic mean-field theory with inclusion of deformations. The calculated binding energies agree well with values from macroscopic mass models. Calculations show that there exists a spherical shell. at N = 184, because the quadrupole deformation at N = 184 is zero. For nuclei near N = 162, there are small prolate deformations.
