Abstract：
The α-decay lifetimes of the newly synthesized superheavy elements are calculated using the α-cluster model and the results are in good agreement with experimental data. This indicates the reliability of the α-cluster model. The theoretical lifetimes based on the Hartree-Fock nuclear mass table are also calculated, which are useful for further theoretical and experimental researches on superheavy nuclei. We have also analyzed the α-decay energies, the separation energies of the last two neutrons and the separation energies of the last two protons of the superheavy nuclei. The shell effect at Z=114 and N=184 is discussed.
