Abstract
The neutron skin thickness of the benchmark nucleus Pb is crucial for our understanding of the equation of state of nuclear matter. In this paper, we discuss the effect of the neutron skin on the flow ratio observables in the semi-isobaric collisions Pb+Pb and Au+Au using iEBE-VISHNU hydrodynamic simulations. Our results suggest that Pb and Au should have the same magnitude of neutron skin thickness to describe the anisotropic flow ratios between the semi-isobaric systems. Our method provides an unconventional way to determine the neutron skin with the existing relativistic heavy ion collision data.
