Description
The neutron skin thickness of the benchmark nuclei 208^Pb is crucial for our understanding of the equation of state of nuclear matter. Several observables in relativistic heavy ion collisions are found to be sensitive to the neutron skin, and the uncertainties from the bulk evolution can be canceled out by the collision of its isobaric partner. In this talk, we discuss the effect of the neutron skin on the ratio observables in semi-isobaric collisions, i.e., 208^Pb + 208^Pb collisions and 197^Au + 197^Au collisions. Our results indicate that the 208^Pb and 197^Au have similar magnitude of neutron skin thickness, as the two isobaric collision systems follow the same scaling behavior. Our results can shed light on the determinations of neutron skin and nuclear symmetry energy in relativistic heavy ion collisions.
