英文摘要: Systematic calculations on the alpha-decay half-lives of heavy and superheavy nuclei are performed within a deformed version of the cluster model, using the modified two-potential approach. The deformed Woods-Saxon potential is employed to calculate the alpha-decay width through a deformed barrier. For comparison the calculated alpha-decay half-lives in the empirical relations are also presented. The present study is initially restricted to even-even nuclei in the heavymass region with N > 126. Then the study is extended to the recentlyobserved heaviest nuclei, including synthesized superheavy elements and isotopes. The alpha-decay half-lives obtained are found to be in good agreement with the experimental data.
