The total and the differential cross sections for the D(gamma,p)n reac
tion have been measured over the photon energy range 100-800 MeV at th
e 855 MeV MAMI Microtron in Mainz. Using the large acceptance detector
DAPHNE in conjunction with the Glasgow tagging spectrometer, high pre
cision results with small systematic errors were obtained, The data ar
e presented in the form of thirty-five angular distributions at c.m. p
roton angles between 30 degrees-160 degrees in 10 degrees intervals an
d at photon energies in steps of 20 MeV. Previous experimental work is
reassessed in the light of the present results and comparison with so
me recent theoretical calculations.
