Kurzbeschreibung (Abstract)
The knowledge of the equation of state (EOS) for neutron-rich matter is fundamental for understanding properties of, e.g., neutron stars, core-collapse supernova, and neutron-rich nuclei. Deriving experimental constraints for the EOS is thus of utmost importance. The parameter for the slope of the symmetry energy at saturation density (L), in the EOS for asymmetric nuclear matter has not yet been sufficiently constrained experimentally. One variable that has been proven to be highly sensitive to L is the neutron-skin thickness, which is the difference between the nuclear root-mean-square (rms) obtained using the density distributions of neutrons and protons in a nucleus. It has been shown that through an accurate measurement of the total neutron-removal cross section, the value of L can be constrained. The R³B setup has been upgraded to now include the neutron detector NeuLAND and the GLAD dipole magnet alongside our tracking setup, which will allow measurements with high momentum resolution and large acceptance. This will allow us to get the accuracy required for constraining L. With this setup, accurate measurements of the total reaction, charge-changing, and neutron-removal cross sections are possible. A first measurement for ¹²⁰Sn has already been completed using the FAIR phase 0 R³B setup at GSI and will be presented here. First results for the charge-changing cross section are also presented along with an outlook for future experiments.
