Abstract

A facility to perform measurements of nuclear reaction rates in which one of the reactants is a radioactive species is described. The value of these reactions to the area of nuclear astrophysics is discussed in detail and calculations of expected yields for selected examples are given. This proposed facility is composed of an on-line isotope separator (ISOL) front-end coupled to a booster post-accelerator stage to raise the energy of a radioactive ion beam to sufficient energies (up to 1.5 MeV/u) to perform these studies. The advantages of this approach are presented along with a discussion of the feasibility of not only obtaining the necessary radioactive beam intensities of the important isotopes, but also of achieving the acceleration necessary. Details of one feasible accelerator system are presented.
