Abstract

The cluster radioactivity of various heavy nuclei have been studied using the modified generalized liquid drop model (MGLDM) with a new statistical cluster preformation probability of Dong et al. [Eur. Phys. J. A 41, 197 (2009)]. The statistical preformation factor obtained obeys the relation for preformation factor or spectroscopic factor, S=Sα(A21)/3 of Blendowske et al. [Phys. Rev. Lett. 61, 1930 (1988)] with Sα=0.063, exactly the same value reported. The predicted half-lives using MGLDM are in agreement with experimental data with standard deviation σ=1.16 and also consistent with other empirical formula predictions. Predictions on decay modes of nuclei, which are energetically allowed but not yet observed, are also done which will be helpful for scientists to design new experiments on cluster radioactivity.

基于统计聚类预形成概率的改进广义液体模型的聚类放射性
本文采用改进的广义液滴模型(MGLDM)和Dong等人提出的新的统计聚类预形成概率,研究了各种重核的聚类放射性。理论物理。[j].农业工程学报,2009(1)。得到的统计预形成因子符合Blendowske等的预形成因子或光谱因子的关系式S=Sα(A2−1)/3。Rev. Lett. 61, 1930 (1988)], Sα=0.063,与报告的值完全相同。用MGLDM预测的半衰期与实验数据基本一致,标准差σ=1.16,与其他经验公式预测的半衰期基本一致。对原子核衰变模式的预测,在能量上是允许的,但还没有被观察到,这将有助于科学家设计新的簇放射性实验。
