High energy angular distribution measurements of the exclusive deuteron photodisintegration reaction

Abstract

The first complete measurements of the angular distributions of the two-body deuteron photodisintegration differential cross section at photon energies above 1.6 GeV were performed at the Thomas Jefferson National Accelerator Facility. The results show a persistent forward-backward asymmetry up to ${E}_{\ensuremath{\gamma}}=2.4\mathrm{GeV},$ the highest-energy measured in this experiment. The Hard Rescattering and the Quark-Gluon string models are in fair agreement with the results.
