The first measurements of the d(γ,p)n differential cross section at forward angles and photon energies above 4 GeV were performed at the Thomas Jefferson National Accelerator Facility (JLab). The results indicate evidence of an angular dependent scaling threshold. Results at θcm=37° are consistent with the constituent counting rules for Eγ4 GeV, while those at 70° are consistent with the constituent counting rules for Eγ1.5 GeV.
