   Abstract:
   In this talk, we discuss an experiment that has been conducted recently at the High Intensity Gamma Source (HIGS) facility at the Duke Free Electron Laser Laboratory (DFELL) on three-body photodisintegration of circularly polarized photons from a longtudinally polarized ³He target at an incident photon energy of 11.4 MeV. The target was based on the technique of spin-exchange optical pumping with hybrid rubidium and potassium vapors. Neutrons from the three-body photodisintegration process were detected in the experiment using liquid scintillator neutron detectors. We also discuss future prospects at HIGS with the Gerasimov-Drell-Hearn (GDH) integral measurement of ³He.
