来自地面实验的EoS:核密度的静态和动态极化

EoS from terrestrial experiments: static and dynamic polarizations of nuclear density

H. Sagawa, S. Yoshida, Li-Gang Cao

摘要:

我们严格审查核物质和中子物质状态方程(EoS)参数使用最好的陆地实验结果。通过与现代相对论和非相对论EDF的RPA结果以及$^{208}$ Pb的等密度巨共振能的最新实验数据的比较,重新检验了核的压缩模量$K_{\infty}$.利用最近的FRDM质量模型和从$(p,p')$实验中提取的$^{48}$ Ca的中子皮,研究了对称能展开系数$J$、$L$和$K_{sym}$.

英文摘要:

We critically examine nuclear matter and neutron matter equation of state (EoS) parameters by using best available terrestrial experimental results. The nuclear incompression modulus $K_{\infty}$ is re-examined in comparisons with RPA results of modern relativistic and non-relativistic EDF and up-to-date experimental data of isoscalar giant monopole resonance energy of $^{208}$Pb. The symmetry energy expansion coefficients $J$, $L$ and $K_{sym}$ are examined by recent FRDM mass model and the neutron skin of $^{48}$Ca extracted from $(p,p')$ experiments.
