  • 摘要: 基于结团形成模型(cluster-formation model,CFM)系统地研究了质子数Z=82,中子数N=126闭壳附近的α衰变母核的α衰变预形成因子Pα。计算结果表明:基于结团形成模型计算得到的Pα线性地依赖于价质子(空穴)Np和价中子(空穴)Nn的乘积。这与前期工作[SUN X D,et al.Phys Rev C,2016, 94 (2):024338;DENG J G,et al.Phys Rev C,2017, 96 (2):024318]得到的结论是一致的,其中,Pα是唯象的且模型依赖的,从α衰变半衰期的理论值和实验值的比值中提取。结合前期工作可以得到这样的结论:对于Z=82,N=126闭壳附近的α衰变母核,其PαNpNn呈线性关系,且价质子-价中子相互作用在α结团预形成中起了很重要的作用。


    In the present work, the α decay preformation factors Pα are systematically studied within the cluster-formation model (CFM) for nuclei around Z=82, N=126 closed shells. The calculations show that the Pα calculated by CFM is linearly dependent on the product of valance protons (holes) and valance neutrons (holes) Np Nn. It is consistent with our previous works[SUN X D, et al. Phys Rev C, 2016, 94 (2):024338; DENG J G, et al. Phys Rev C, 2017, 96 (2):024318], which Pα are model-dependent and extracted from the ratios of calculated α decay half-lives to experimental data. Combining with our previous works, we confirm that the Pα is linearly dependent on the NpNn for nuclei around Z=82, N=126 shell closures. In addition, the valance proton-neutron interaction plays a key role in the α preformation.
