Three-body photodisintegration of 3He with double polarizations at incident photon energies E 12.8 MeV and 14.7 MeV

ORAL

Abstract

We report on the study of three-body photo-disintegration of polarized $^3$He using a circularly polarized $\gamma$ beam at incident photon energies 12.8 MeV and 14.7 MeV. The experiment was carried out at the High Intensity $\gamma$ Source (HI$\gamma$S) facility located at Triangle Universities Nuclear Laboratory. A high-pressure $^3$He cell was employed as target and it was polarized using the spin exchange optical pumping (SEOP) technique of hybrid alkali. The neutrons from the three-body photo-disintegration were detected using 16 liquid scintillator fast neutron detectors positioned in the reaction plane at 8 angles varying from 30$^\circ$ to 165$^\circ$. Preliminary results on asymmetry and spin-dependent differential cross sections for both energies will be presented and compared with the three-body calculations using both CD Bonn and AV18 potentials.
