  The high energy two-body photodisintegration of the deuteron is an ideal
reaction for the identification of quark effects in the nuclei. In particular,
the study of this reaction in the few GeV region can clarify the transition
from the nucleonic degrees of freedom to the QCD picture of hadrons. The CLAS
large angle spectrometer of Hall B at TJNAF allowed for the first time to
measure the differential cross section for photon energy between 0.5 and 3 GeV,
over all proton angles between 10 and 140 degrees in the laboratory frame.
Preliminary results from the analysis of 30% of the total statistic accumulated
is shown. These results are in good agreement with the available data, and are
well described by the recent calculation of the deuteron photodisintegration
cross section derived in the framework of the Quark Gluon String Model.
