本文在核壳层模型的框架下,系统地计算了含N50和N50的核的允许衰变半衰期。最近的一项研究表明,该区的某些核属于反转岛。我们使用KB3G有效相互作用对fp壳层核进行了计算。在Ni、Cu和Zn的情况下,我们使用JUN 45有效相互作用。Q值,半衰期,激发能,logft值,和分支分数的理论结果进行了讨论,并与实验数据进行比较。在Ni区域中,我们还将我们的计算结果与最近的实验数据进行了比较(Xu等人2014 Phys.Rev.Lett. 113 032505)。与QRPA相比,本结果与半衰期的实验数据一致。
In the present work we calculate the allowed -decay half-lives of nuclei with and N 50 systematically under the framework of the nuclear shell model. A recent study shows that some nuclei in this region belong to the island of inversion. We perform calculation for fp shell nuclei using the KB3G effective interaction. In the case of Ni, Cu, and Zn, we used the JUN45 effective interaction. Theoretical results of Q values, half-lives, excitation energies, logft values, and branching fractions are discussed and compared with the experimental data. In the Ni region, we also compared our calculated results with recent experimental data (Xu et al 2014 Phys. Rev. Lett. 113 032505). The present results agree with the experimental data of half-lives in comparison to QRPA.
