The first measurements of the d(gamma,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 theta{sub cm} = 37{sup o} are consistent with the constituent counting rules for E{sub gamma}{approx}> 4 GeV, while those at 70{sup o} are consistent with the constituent counting rules for E{sub gamma} {approx}> 1.5 GeV.
