论文摘要
在目前的工作中，我们系统地研究了$α$衰减的半衰期，为170个均匀的核，$ 60 \ leqslant z \ leqslant 118 $在两势方法中，而$α$衰减预成型因子$p_α$由集群形式模型获得。计算的结果可以很好地再现实验数据。此外，我们扩展了该模型，以预测$α$衰减的半衰期为64个均匀的核，$ 104 \ leqslant z \ leqslant 128 $，其$α$衰减是能量允许或观察到但尚未量化的。为了进行比较，即D. poenaru $ {et \ al。} $ [\ href {https://doi.org/10.1209/0295-5075/77/77/62001} {europhys {europhys。 Lett。 \ textbf {77}（2007）62001}]和udl由C. qi $ {et \ al。} $ [\ href {https://doi.org/10.1103/physrevlett.103.072501} {phys。莱特牧师。 \ textbf {103}（2009）072501}]。这些模型的预测结果基本一致。同时，通过分析$α$衰减能量的变化趋势$q_α$的\ emph {z} = 118、120、122、122、124、126、126和128同位素核，随着中子数的增加\ emph {n}的增加，以及$α$ d衰减$p_α$p_α$的数字的增加，甚至是 - \ emph {n}，\ emph {n} = 178可能是一个新的中子魔术号码。
In present work, we systematically study the $α$ decay half-lives of 170 even-even nuclei with $60 \leqslant Z \leqslant 118$ within the two-potential approach while the $α$ decay preformation factor $P_α$ is obtained by the cluster-formation model. The calculated results can well reproduce the experimental data. In addition, we extend this model to predict the $α$ decay half-lives of 64 even-even nuclei with $104 \leqslant Z \leqslant 128$ whose $α$ decay is energetically allowed or observed but not yet quantified. For comparing, the two famous models i.e. SemFIS proposed by D. Poenaru ${et\ al.}$ [\href {https://doi.org/10.1209/0295-5075/77/62001}{Europhys. Lett. \textbf{77} (2007) 62001}] and UDL proposed by C. Qi ${et\ al.}$ [\href {https://doi.org/10.1103/PhysRevLett.103.072501}{Phys. Rev. Lett. \textbf{103} (2009) 072501}] are used. The predicted results of these models are basically consistent. At the same time, through analyzing the changing trend of $α$ decay energy $Q_α$ of \emph{Z} = 118, 120, 122, 124, 126 and 128 isotopes nuclei with the increasing of neutron number \emph{N} and that of $α$ decay preformation factor $P_α$ of those isotopes even-even nuclei with the increasing of neutron number \emph{N}, \emph{N} = 178 may be a new neutron magic number.
