Collinear laser spectroscopy at NSCL/FRIB — •Kristian König1,2, Ronald Garcia-Ruiz3, Kei Minamisono2, and Wilfried Nörtershäuser1 — 1Institut für Kernphysik, TU Darmstadt, Germany — 2Facility for Rare Isotope Beams, Michigan State University, USA — 3Massachusetts Institute of Technology, USA
The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University was recently upgraded to the Facility for Rare Isotope Beams (FRIB). With in-flight fragmentation, rare isotope beams from all over the nuclear chart can be produced and investigated, e.g., with collinear laser spectroscopy at the BECOLA setup. In this talk, we will summarize the latest results on Nickel, Scandium and Silicon that gave new insights in the nuclear structure at the neutron shell closures at N=20 and 28. Furthermore, the investigation of the nuclear charge radius of mirror nuclei allowed us to constrain L, the slope parameter of the nuclear equation of state. Our result is consistent with results derived from the dipole polarizability and neutron star mergers. The capabilities of BECOLA in the FRIB era will be discussed as well as the status of the currently ongoing upgrade that will allow us to perform the more sensitive collinear resonance ionization spectroscopy with particle detection (RISE).
