TOF-Bρ mass measurements of neutron-rich nuclei at the NSCL — •Sebastian George for the TOF-BRho collaboration — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Nuclear masses of exotic nuclei towards the driplines are important key parameters for the understanding of nuclear structure of very exotic nuclei and the description of astrophysical processes. Particularly the evolution of matter in the crust of accreting neutron stars incorporates nuclei far away from stability and is limited by the use of theoretical mass models. Time-of-flight-Bρ (TOF-Bρ) mass spectrometry allows the mass determination of such exotic species. The method has shown the potential to access short-lived and rarely produced nuclides at several radioactive beam facilities. Here the setup of the TOF-Bρ experiment at the National Superconducting Cyclotron Laboratory (NSCL) at the Michigan State University is presented. Results of mass measurements in the region of neutron-rich argon to iron are discussed in the context of their impacts on nuclear astrophysics and nuclear structure.
