论文摘要
通过在完整的DIRAC空间中求解相对论的Brueckner-Hartree-fock方程,可以阐明有关有效dirac质量在不对称核物质中的同胞依赖性的长期争议。饱和密度的对称能量及其斜率参数为$ e _ {\ text {sym}}(ρ_0)= 33.1 $ MEV和$ L = 65.2 $ MEV,与经验和实验值一致。进一步的应用程序预测中子星半径$ r_ {1.4m_ \ odot} \大约12 $ km和中子星的最大质量$ m _ {\ text {max}} \ leq 2.4m_ \ odot $。
The long-standing controversy about the isospin dependence of the effective Dirac mass in ab initio calculations of asymmetric nuclear matter is clarified by solving the relativistic Brueckner-Hartree-Fock equations in the full Dirac space. The symmetry energy and its slope parameter at the saturation density are $E_{\text{sym}}(ρ_0)=33.1$ MeV and $L=65.2$ MeV, in agreement with empirical and experimental values. Further applications predict the neutron star radius $R_{1.4M_\odot}\approx 12$ km and the maximum mass of a neutron star $M_{\text{max}}\leq 2.4M_\odot$.
