Part of the R3B physics program is to constrain the density dependence of the symmetry energy in the nuclear equation of state near saturation density by measuring the neutron-skin thickness of exotic nuclei via fragmentation reactions. For this purpose, it is essential to quantify the uncertainty of the reaction model under ideal conditions. In this work, the precisely measured total interaction cross sections of 12C+12C collisions at relativistic energies are presented and compared to theoretical predictions based on a Glauber reaction model.
