Description

The first measurements of differential cross sections for deuteron photo-disintegration at photon energies up to 4 GeV were performed at the Thomas Jefferson National Accelerator Facility early in 1996. Cross section results for D(γ,p)n at proton center of mass angle of 35 degree, 53 degree and 90 degree will be presented. These results are in good agreement with previous measurements at low energy and extend to higher energies where data were previously unavailable. The 90 degree degree data show behavior consistent with the constituent counting rules up to 4 GeV and are also in fair agreement with the asymptotic meson exchange model. The 37 degree and 53 degree data do not show clear signs of counting rule behavior, although a threshold in transverse momentum for the onset of scaling cannot be excluded. copyright 1997 American Institute of Physics
