Abstract: An improved semi-analytic approach to the barrier penetration probability is developed in the frame work of the Wentzel-Kramers-Brillouin (WKB) approximation. It is used to calculate decay half-lives and preformation probabilities for a set of 304… read more here.

DOI: 10.1088/1402-4896/ac619d
Abstract: α-decay half-lives of superheavy nuclei have been studied using modified Gamow-like model and improved empirical formulas. The empirical formulas used in the study are Viola-Seaborg semi-empirical formula, universal decay law (UDL), Denisov-Khudenko formula (DK), Royer… read more here.

DOI: 10.1088/1674-1137/41/6/064101
Abstract: We considered the systematics of $\alpha$-decay (AD) half-life (HL) of super-heavy nuclei versus the decay energy and the total $\alpha$-kinetic energy. We calculated the HL using the experimental Q_{$\alpha$} values. The computed half-lives are compared… read more here.

DOI: 10.1103/physrevc.96.024318
Abstract: In the present work, the unfavored $\ensuremath{\alpha}$-decay half-lives and $\ensuremath{\alpha}$ preformation probabilities of closed-shell nuclei related to ground and isomeric states around $Z=82, N=82$ and 126 shell closures are investigated by adopting the two-potential approach… read more here.
