Nuclear-structure studies with direct reactions and particle-gamma coincidences at FSU and NSCL

ORAL  · Invited

Abstract

If carefully chosen, single-nucleon transfer and light-ion inelastic scattering experiments can provide enhanced selectivity to specific nuclear structure phenomena. In this invited talk, I will present an overview of direct-reaction studies performed at the John D. Fox Laboratory of Florida State University and at the National Superconducting Cyclotron Laboratory (NSCL) of Michigan State University.

For the NSCL part, I will report on recent inelastic proton scattering experiments performed with the gamma-ray tracking array GRETINA, the S800 spectrograph, and the NSCL/Ursinus Liquid Hydrogen Target to study octupole excitations in the rare isotopes 72Se and 74,76Kr. Plans for continuing the program at the Facility for Rare Isotope Beams (FRIB) will be mentioned.

At the Fox Lab, we have very recently commissioned the first CeBr3 detectors of the CeBrA array. CeBrA will be used for particle-gamma coincidence experiments at the FSU Super-Enge Split-Pole Spectrograph (SE-SPS) to study, e.g., the Pygmy Dipole Resonance via one-neutron transfer. New results from first SE-SPS singles as well as first SE-SPS+CeBrA coincidence experiments will be highlighted.
