论文摘要

虽然已经确定了一态和两中子基态晕核的现象,但弱结合对核激发特性的影响在很大程度上尚未得到探索。在$^{40} $ mg中的最新数据中,我们研究了使用$^{40} $ mg的已知属性探索并说明可能的粒子核心耦合方案及其对低亮型激发光谱的影响。

While the phenomenon of one- and two-neutron ground-state halo nuclei is well established, the effects of weak binding on nuclear excitation properties remain largely unexplored. Motivated by this question and by recent data in $^{40}$Mg we investigate the coupling of weakly bound (halo) valence neutrons to a core using the known properties of $^{40}$Mg to explore and illustrate possible particle-core coupling schemes and their impact on the low-lying excitation spectrum.
