Abstract

The neutron skin thickness of the benchmark nucleus 208^{208}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 208^{208}Pb+208^{208}Pb and 197^{197}Au+197^{197}Au using iEBE-VISHNU hydrodynamic simulations. Our results suggest that 208^{208}Pb and 197^{197}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.
