DOI: 10.1103/physrevc.100.014309
Abstract: Half-lives of ${\ensuremath{\beta}}^{+}$ decay and electron capture are studied in some selected superheavy nuclei produced in hot-fusion reactions, namely, $^{290}\mathrm{Fl}$, $^{293}\mathrm{Mc}$, $^{294}\mathrm{Lv}$, and $^{295}\mathrm{Ts}$. The nuclear structure is described microscopically from deformed self-consistent Skyrme Hartree-Fock… read more here.
