Four-body Microscopic Cluster Model Calculation of 7Li and 7Be Nuclei

  • 摘要: 深入了解7Li和7Be原子核的基态和激发态性质对解释Li,Be等元素在原初宇宙中的产生和相关反应具有重要意义。目前多数关于7Li或7Be的微观模型计算主要考虑其中的α+t或α+3He两体团簇结构。本工作采用四体微观团簇模型开展了理论研究,结果表明,考虑三体和四体团簇结构能够有效优化计算所得的基态和激发态波函数,使能谱和核半径等物理量更加接近实验数据。

     

    Abstract: Understanding deeply the properties of the ground and excited states of 7Li and 7Be is important for explaining the creation and related reactions of Li and Be isotopes in the primordial universe. Most of the cluster model calculations of 7Li or 7Be consider only the \alpha+\mathrmt or α+3He two-body cluster structure. The present work conducted theoretical research employing a four-body microscopic cluster model. The results show that, by considering the three- and four-body cluster structures, the calculated wave functions of ground and excited states are effectively modified. The obtained observables such as energy spectra and nuclear radii reproduce better the experimental data, compared to that in the two-body calculation.
