论文摘要
在Fermi Energy域中$^{64,58} ni $反应在$^{64,58} ni $上形成的准投影的Isospin扩散在Boltzmann-Uehling-Uehlenbeck运输模型的框架内研究了Fermi Energy域中的ni $。重新审视可观察到的众所周知的同源传输比，目的是确保实验数据和理论计算之间的最佳比较，并减少在状态参数的经验方程中提取当前的不确定性。我们表明，isospin的传输比对所有低订单ISOVECTOR参数（$ e_ {sym} $，$ l_ {sym} $和$ k_ {sym} $）敏感。我们证明，状态方程的现实模型，涵盖了目前影响中子星静态可观察物的理论描述的不确定性，只要在弹丸残余物的质子比的质子比，可以通过精确测量弹丸残余的质子比率，从而有效地歧视中子扩散实验。
The isospin diffusion of the quasi-projectile formed in the $^{64,58}Ni$ on $^{64,58}Ni$ reactions in the Fermi energy domain is investigated in the framework of the Boltzmann-Uehling-Uhlenbeck transport model. The well known isospin transport ratio observable is revisited, with the aim of insuring an optimal comparison between experimental data and theoretical calculations and reducing the present uncertainties in the extraction of empirical equation of state parameters. We show that isospin transport ratios are sensitive to all the low order isovector parameters ($E_{sym}$, $L_{sym}$ and $K_{sym}$). We demonstrate that realistic models of the equation of state, covering the uncertainty that presently affects the theoretical description of neutron stars static observables, can be effectively discriminated by isospin diffusion experiments, provided the neutron to proton ratio of the projectile remnant is precisely measured as a function of centrality.
