| 英文摘要 | Recently discovered alpha decays with new or improved data, covering naturally occurring alpha emitters with long lifetimes, short-lived ones approaching the proton drip line, and decays of heavy and superheavy elements, have been studied in a systematic investigation within the modified two-potential approach for deformed nuclei by constructing the microscopic double-folding potential. It is found that the experimental half-lives are well reproduced in the density-dependent cluster model. Some predictions on natural alpha emitters and alpha decays of several proton emitters are made in this study. Moreover, the alpha-decay half-lives of even-even superheavy nuclei with Z = 110-114 and N = 184-194 are estimated to pursue the quite stable nuclei around the proton Z similar to 114 and neutron N similar to 184 shell closures. These predictions can be useful for future experiments aimed at searching for long-lived natural elements. |
