A key ingredient in any theoretical description of heavy ion collisions is the spatial distribution of the nucleons inside the nuclei. Traditionally, both protons and neutrons have been distributed in an identical way via the Woods-Saxon distribution in the nucleus. However it has been experimentally measured that this assumption is not correct: there are more neutrons distributed on the outer layers of the nucleus than protons, the so-called neutron skin effect. By initializing heavy nuclei like Au or Pb with a neutron skin within the transport model SMASH, we study the influence of this novel feature on the zeroth component of the baryonic isospin current jµ for different impact parameters and √s. The aim of this study is to make predictions for the isobar systems Zr and Ru run at RHIC in 2018.
