Figure 1: The new Facility for Rare Isotope Beams (FRIB) will be able to produce isotopes along the neutron dripline (light grey line) for elements up to argon. The colors correspond to the rates, in particles per second (pps), with which various isotopes can be produced. The experimental and theoretical tools used by Winkler et al. to study argon-$47$ and argon $48$ (inset) will provide an important framework with which to study neutron-rich isotopes at the FRIB.
