【 摘 要 】

This thesis presents an experimental study of the D(gamma,p)n breakup channel of the photodisintegration of deuterium in which both the total cross section (sigmatot, and the differential cross section, dsigma/dO, have been measured over the photon energy range 200-600 MeV. The experiment was performed at the recently completed tagged photon facility of the 855 MeV Microtron MAMI-B, at the Mainz Institut fur Kernphysik, Germany. The experiment used the GLASGOW tagging spectrometer in conjunction with the large acceptance detector DAPHNE achieving systematic and statistical errors of a few percent and extending the range of photon energies previously studied. Data taking started in May 1992, as part of the first round of approved experiments at MAMI-B. The GLASGOW tagging spectrometer was used to determine the photon energy with a resolution of about 2 MeV at intensities up to 5 x 10e5 photons per channel. Photon flux normalisation was determined to +/- 2%. A 270 mm long cryogenic target filled with liquid deuterium was placed coaxially with the beam. Protons were detected in the large acceptance tracking detector DAPHNE (3.7pi steradians) whose coverage of the azimuthal angle was complete and whose polar angular range was 21
