Complete angular distribution measurements of two-body deuteron photodisintegration between 0.5 and 3GeV

Abstract

Nearly complete angular distributions of the two-body deuteron photodisintegration differential cross section have been measured using the CEBAF Large Acceptance Spectrometer detector and the tagged photon beam at the Thomas Jefferson National Accelerator Facility. The data cover photon energies between $0.5$ and $3.0\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}$ and center-of-mass proton scattering angles $10\ifmmode^\circ\else\textdegree\fi{}--160\ifmmode^\circ\else\textdegree\fi{}$. The data show a persistent forward-backward angle asymmetry over the explored energy range, and are well described by the nonperturbative quark gluon string model.
