提出了一个基于由反质子原子方法得到的一系列核的中子皮厚度的数据约束对称能的密度依赖的方法。首先,给出原子核的中子皮厚度与原子核的电荷数和同位旋不对称度两者的相关性,并从已有的由反质子原子方法得到的一系列核的中子皮厚度的数据得到这些原子核的中子皮厚度与这些原子核的电荷数和同位旋不对称度的最佳关联系数。然后,采用推广的Thomas-Fermi近似(ETF2)结合Skyrme能量密度泛函和库仑能量密度方法系统地计算这些核的中子皮厚度。 A density-dependent method of constraining symmetry energy based on a series of neutron skin thicknesses obtained by the antiproton atomic method is proposed. First, the correlation between the neutron skin thickness of the nucleus and the charge number of the nuclei and the asymmetry degree of the isospin is given. From the data of the existing neutron skin thickness obtained from the anti-proton atom method The best correlation coefficient between the neutron skin thickness of these nuclei and the charge number and the isospin asymmetry of these nuclei. Then, the neutron skin thickness of these nuclei was systematically calculated using the extended Thomas-Fermi approximation (ETF2) combined with the Skyrme energy density functional and coulomb energy density methods.
