Abstract: The ground-state binding energies,alpha-decay energies,and quadrupole deformations of nuclei in the Z=114 isotopes are systematic calculated by the macroscopic-microscopic(MM) model for Nilsson potential.The calculated results are compared with experimental data and with other theoretical results.It is shown that the calculated results are close to other theoretical results and consistent with the experimental data,which indicates that the MM model is reliable in describing the properties of superheavy nuclei.Studies on the shell effects and deformations show that Z=114 and N=184 are closed shells in the MM model.
