论文摘要
使用反对称分子动力学以及共鸣组方法（AMD+RGM）讨论了31Ne变形光环的性质。 AMD+RGM计算描述了基态的较大中子半径，并揭示了基态由核心激发的组件支配。还通过应用耦合常数的分析延续来研究共振状态。发现第一个激发态（5/2-状态）也以核心激发的组件为主，并且具有较小的衰减宽度，而第二个激发态（7/2-状态）在价中子中以$ f $ - 波的价值为主导，并以$ f $ - 波（耦合到30ne的基态）。
The properties of the deformed halo of 31Ne were discussed using the antisymmetrized molecular dynamics plus resonating group method (AMD+RGM). The AMD+RGM calculations describe a large neutron radius for the ground state and reveal that the ground state is dominated by core-excited components. The resonant states were also investigated by applying the analytical continuation of the coupling constant. It was found that the first excited state (the 5/2- state) is also dominated by core-excited components and has a small decay width, whereas the second excited state (the 7/2- state) is dominated by the valence neutron in the $f$-wave coupled to the ground state of 30Ne.
