论文摘要
对核的结合能的准确估计远非远离稳定性，而实验室无法产生的稳定性对于我们对天体物理场景中核过程的理解至关重要。基于能量密度功能的模型表明，它们能够在保留牢固的微观基础的同时，能够重现所有已知均方误差的已知质量，其均方根误差要比800 KEV更好。但是，最近在[M. Hukkanen等人，Arxiv：2210.10674]，最近的BSKG1模型未能说明对奇数核特有的结合能的贡献，并且可以使用适当的质量差异公式来研究。我们在这里分析了有关此类公式的三个最近三个微观质量模型的（缺乏）性能（缺乏）性能，并检查了将来这种缺乏症的可能性。
Accurate estimates of the binding energy of nuclei far from stability that cannot be produced in the laboratory are crucial to our understanding of nuclear processes in astrophysical scenarios. Models based on energy density functionals have shown that they are capable of reproducing all known masses with root-mean-square error better than 800 keV, while retaining a firm microscopic foundation. However, it was recently pointed out in [M. Hukkanen et al., arXiv:2210.10674] that the recent BSkG1 model fails to account for a contribution to the binding energy that is specific to odd-odd nuclei, and which can be studied by using appropriate mass difference formulas. We analyse here the (lacking) performance of three recent microscopic mass models with respect to such formulas and examine possibilities to remedy this deficiency in the future.
