I will present recent results from beta-gamma and beta-NMR spectroscopy studies of very neutron-deficient nuclei produced via projectile fragmentation at National Superconducting Cyclotron Laboratory (NSCL). Beta-delayed gamma-ray studies have been enhanced at NSCL with commissioning of the RF Fragment Separator, which eliminates long-lived contaminants that proved troublesome in past fragment-decay correlation measurements based on position and time. A new high-power NMR system has been completed and used to measure ground-state quadrupole moments for the first time at NSCL. Future opportunities for beta spectroscopy experiments with low-energy (~30 keV) beams at NSCL will also be discussed. Research supported in part by NSF grant PHY-06-06007.
