Abstract
The first measurements of the d(gamma, p)n differential cross section at fo rward angles and photon energies above 4 GeV were performed at the Thomas J efferson National Accelerator Facility (JLab). The results indicate evidenc e of an angular dependent scaling threshold. Results at theta (cm) = 37 deg rees are consistent with the constituent counting rules for E-gamma greater than or similar to 4 GeV, while those at 70 degrees are consistent with th e constituent counting rules for E-gamma greater than or similar to 1.5 GeV .
