Abstract:The differential cross section for two-body deuteron photodisintegration was measured during experiment E89-012 which took place at the Continuous Electron Beam Accelerator Facility in the Spring of 1996. The newly commissioned High Momentum Spectrometer was used to detect the recoil proton of the photodisintegration reaction at center of mass angles 36°, 52°, 69°, and 89° with incident photon energies 0.8, 1.6, 2.4, 3.2, and 4.0 GeV. Constituent counting rules predict that the invariant cross section should scale as s -11 at asymptotic energies. Previous data show evidence of this scaling starting at about Egamma = 1.2--1.5 GeV for theta cm = 90°. Results from this experiment show that asymptotic scaling is evident for thetacm = 89° and 69°, but no evidence of asymptotic scaling is seen for theta cm = 52° and 36°. Experimental results disagree with the prediction given by the reduced nuclear amplitude model. Comparisons of data to other theoretical predictions given by meson-exchange theories, asymptotic amplitudes, and quark-gluon string model are also shown.
