| 英文摘要 | The alpha-decay half-lives of recently synthesized superheavy nuclei (SHN) are investigated by employing a unified fission model (UFM) and Royer's analytical formula (2000 J. Phys. G: Nucl. Part. Phys. 26 1149). The good agreement with the experimental data indicates the UFM and the analytical formula are useful tools to investigate these alpha-decays. A modified formula is proposed for determining the spontaneous fission half-lives based on Swiatecki's formula, including the microscopic shell correction and isospin effect. The spontaneous fission half-lives for heavy and SHN in regions from Th to Fl are calculated systematically. Experimental data are well reproduced by the modified Swiatecki formula. The competition between alpha-decay and spontaneous fission is analyzed in detail and the decay modes are predicted for the unknown cases. |
