Abstract
The first measurements of the differential cross section for the d(gam ma,p)n reaction up to 4.0 GeV were performed at the Continuous Electro n Beam Accelerator Facility (CEBAF) at Thomas Jefferson Laboratory. We report the cross sections at the proton center-of-mass angles of 36 d egrees, 52 degrees, 69 degrees, and 89 degrees. These results are in r easonable agreement with previous measurements at lower energy. The 89 degrees and 69 degrees data show constituent-counting-rule behavior u p to 4.0 GeV photon energy. The 52 degrees and 36 degrees data disagre e with the counting-rule behavior. The quantum chromodynamics; (QCD) m odel of nuclear reactions involving reduced amplitudes disagrees with the present data. [S0031-9007(98)07676-5].
