Constraints on the Symmetry Energy from PREX-II in the Multimessenger Era

Tong-Gang Yue, Lie-Wen Chen, Zhen Zhang +1

The neutron skin thickness $\Delta r_{\mathrm{np}}$ of heavy nuclei is essentially determined by the symmetry energy density slope $L(\rho )$ at ${\rho }_c=0.11{\mathrm{fm}}^{-3}\approx 2/3{\rho }_0$ ($ρ_…
