论文摘要
In this paper, we have calculated the $α$-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 $WS4$ $α$-decay energy and the semi-classical渗透概率的斜视 - kramer-brillouin近似。此外，我们在集群形式模型中包括了预制因子。我们已经调查了上述地区的魔术数量和子语数。概率高162、178和184被预测为中子魔术数。我们还确认，我们预测的半衰期与从Royer，VSS，UDL和Semfis2等半经验关系获得的同意之间有很好的共识。
In this paper, we have calculated the $α$-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 $WS4$ $α$-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.
