Ground State Properties of Superheavy Nuclei in Macroscopic-Microscopic Model

The ground state properties of superheavy nuclei are systematicallycalculated by the macroscopic-microscopic (MM) model with theNilsson potential. The calculations well produced the ground statebinding energies, α-decay energies, and half lives of superheavy nuclei. The calculated results are systematically compared with available experimental data. The calculated results are also compared with theoretical results from other MM models and from relativistic mean-field model. The calculations and comparisonsshow that the MM model is reliable in superheavy region and that theMM model results are not very sensitive to the choice of microscopicsingle-particle potential.
