论文摘要
我们将游戏壳模型应用于研究$^{25-31} $ f同位素。由于在其中正确处理了核之间的相关性和连续耦合，因此可以精确分析$^{31} $ f的结构形状。为此，在中子富含中子的氟同位素中计算了一个核子密度，根平方半径和相关密度。然后建议$^{31} $ f表现出由连续耦合和核子核子相关性构建的两中性光环结构。
We apply the Gamow shell model to study $^{25-31}$F isotopes. As both inter-nucleon correlations and continuum coupling are properly treated therein, the structure shape of $^{31}$F at large distance can be analyzed precisely. For this, one-nucleon densities, root-mean square radii and correlation densities are calculated in neutron-rich fluorine isotopes. It is then suggested that $^{31}$F exhibits a two-neutron halo structure, built from both continuum coupling and nucleon-nucleon correlations.
