We present an estimate of the yield of hard probes expected for collisions of the isobars 4496Ru and 4096Zr at collision energies reachable at RHIC and the LHC. These yields are proportional to the number of binary nucleon-nucleon interactions, which is characteristically different due to the presence of the large neutron skin in 4096Zr. This provides an independent opportunity to measure the difference between the neutron skin of 4496Ru and 4096Zr, which can provide an important constraint on the Equation of State of cold neutron-rich matter.
