Nuclear Spectroscopy with Radioactive Ion Beams: Latest Results from HRIBF
At the Holifield Radioactive Ion Beam Facility more than 120 beams of p-rich and n-rich radioactive ions with a wide range of intensities, purities and energies are now available to carry out pioneering studies of the study of reactions of far-from-stability nuclei. These radioactive ion beams provide a unique opportunity for a whole class of measurements that could never before be applied. A recent highlight has been the acceleration of "pure" beams of fission fragments such as 82Ge (T1/2=4.6s) and 132Sn (T1/2=40s). These semi-magic and doubly-magic nuclei are important bench marks within the chart of nuclides, because they are constraints for the shell-model parameter sets. We have develop specialized experimental tools and techniques for studies in nuclear astrophysics, reaction spectroscopy, and nuclear structure research with radioactive ion beams. We will discuss some of the challenges encountered in recent experiments in fusion, breakup, Coulomb-excitation, transfer, resonance scattering and mass measurements with radioactive ion beams. * Managed by UT-Battelle, LLC, for the U.S. Department of Energy under contract DE-AC05-00OR22725
