(\alpha\)-decay properties of even-even superheavy nuclei

In this paper, we have calculated the \(\alpha\)-decay half-lives of superheavy nuclei with \(106 \leq Z \leq 126\) and a neutron number of \(150 \leq N \leq 200\) within proximity potentials and deformed-spherical Coulomb potentials by using \(WS4\) \(\alpha\)-decay energy and the semi-classical We...

Summary:In this paper, we have calculated the \(\alpha\)-decay half-lives of superheavy nuclei with \(106 \leq Z \leq 126\) and a neutron number of \(150 \leq N \leq 200\) within proximity potentials and deformed-spherical Coulomb potentials by using \(WS4\) \(\alpha\)-decay energy and the semi-classical Wentzel-Kramers-Brillouin approximation for penetration probability. Besides, we have included the preformation factor within the cluster-formation model. We have investigated magic numbers and submagic numbers in the mentioned region; with high probability 162, 178, and 184 are predicted as neutron magic numbers. We also have confirmed that there is good agreement between our predicted half-lives and the ones obtained from semiempirical relationships such as Royer, VSS, UDL, and SemFIS2.
