Abstract
Recently discovered decays with new or improved data, covering naturally occurring 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 emitters and decays of several proton emitters are made in this study. Moreover, the -decay half-lives of even-even superheavy nuclei with –114 and –194 are estimated to pursue the quite stable nuclei around the proton and neutron shell closures. These predictions can be useful for future experiments aimed at searching for long-lived natural elements.
