Abstract
In this paper, we have calculated the $\ensuremath{\alpha}$-decay half-lives of superheavy nuclei with $106\ensuremath{\le}Z\ensuremath{\le}126$ and a neutron number of $150\ensuremath{\le}N\ensuremath{\le}200$ within proximity potentials and deformed-spherical Coulomb potentials by using $WS4$ $\ensuremath{\alpha}$-decay energy and the semiclassical 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.
