Abstract
The R<sup loc="post">3</sup>B (Reactions with Relativistic Radioactive Beams) experiment as a major instrument of the NUSTAR collaboration for the research facility FAIR in Darmstadt is designed for kinematically complete studies of reactions with high-energy radioactive beams. Part of the broad physics program of R<sup loc="post">3</sup>B is to constrain the asymmetry term in the nuclear equation-of-state and hence improve the description of highly asymmetric nuclear matter (e.g., in neutron stars). For a precise determination of the neutron-skin thickness – an observable which is directly correlated with the symmetry energy in theoretical calculations – by measuring absolute fragmentation cross sections, it is essential to quantify the uncertainty and challenge the reaction model under stable conditions. During the successful FAIR Phase-0 campaign of R<sup loc="post">3</sup>B, we precisely measured the energy dependence of total interaction cross sections in <sup loc="post">12</sup>C+<sup loc="post">12</sup>C collisions, for a direct comparison with calculations based on the eikonal reaction theory.
