论文摘要
我们研究了各种反应通道对相互作用，反应，电荷改变和中子变横截面的贡献。目的是研究中子恒星结构的状态方程（EOS）方程（EOS）的对称能量分量之间的关系。我们已经比较了从各种实验技术中提取的中子皮与用Hartree-fock-Bogoliubov计算获得的，该技术具有23个Skyrme，并在相对论均值场方法中使用了8个密度依赖性相互作用。我们已经表明，鉴于实验数据中广泛的不确定性，无法在最佳的EO上得出任何特定的结论。我们进一步研究了使用中子变化反应来评估中子皮肤中中子皮的同胞依赖性的前景。
We investigate the contributions of various reaction channels to the interaction, reaction, charge-changing and neutron-changing cross sections. The goal is to investigate the relation between microscopic interactions and the symmetry energy component of the equation of state (EoS) of interest for the structure of neutron stars. We have made a comparison of the neutron skins extracted from diverse experimental techniques with those obtained with Hartree-Fock-Bogoliubov calculations with 23 Skyrme and with 8 density-dependent interactions used in the relativistic mean field method. We have shown that no particular conclusion can be drawn on the best EoS in view of the wide range of uncertainty in the experimental data. We have further investigated the prospects of using neutron-changing reactions to assess the isospin dependence of the neutron-skin in neutron-rich nuclei.
