Neutron skins of heavy nuclei and tidal deformability of neutron star

Abstract

In this paper, I have discussed the numerical predictions for the neutron-skin thickness (NST) of various finite nuclei starting from ${}^{40}$Ca to ${}^{238}$U using recently developed effective relativistic mean-field models G3 and IOPB-I \cite{G3, IOPB}. The calculated results are compared with the PREX-II data, and the experiment has been done with antiprotons at CERN. Further, I have also calculated the dimensional tidal deformability of a canonical neutron star 1.4$M_{\odot }$ and compared it with the recent observation of GW1701817.
