论文摘要
最近的实验突破确定了氟和霓虹同位素的最后一个富含中子的核。基于这一发现，我们在相对论平均场（RMF）模型中对$ z = 9、10、11、12 $同位素进行理论研究。从PK1参数化中假设平均场参数，并且配对相关性用RMF模型中最近提出的粒子数保护BCS（FBCS）方法描述。我们表明，FBCS方法在重现氟和霓虹同位素的实验结果中起着至关重要的作用。此外，我们预测$^{39} $ na和$^{40} $ mg是钠和镁同位素中的最后一个富含中子的核。
A recent experimental breakthrough identified the last bound neutron-rich nuclei in fluorine and neon isotopes. Based on this finding, we perform a theoretical study of $Z=9, 10, 11, 12$ isotopes in the relativistic mean field (RMF) model. The mean field parameters are assumed from the PK1 parameterization, and the pairing correlation is described by the particle number conservation BCS (FBCS) method recently formulated in the RMF model. We show that the FBCS approach plays an essential role in reproducing experimental results of fluorine and neon isotopes. Furthermore, we predict $^{39}$Na and $^{40}$Mg to be the last bound neutron-rich nuclei in sodium and magnesium isotopes.
