We are developing approaches needed to determine neutron-induced reactions on radioactive isotopes for experiments at the Facility for Rare Ion Beams. We will develop direct measurement techniques for long-lived radioisotopes, indirect approaches for isotopes too short-lived to be accessed with direct measurements, and a microscopic and unified description of reacting nuclei that moves beyond empirical models.
