We discuss the high energy photodisintegrataion of light nuclei in which theenergy of the absorbed photon is equally shared between two nucleons in thetarget. For these reactions we investigate the model in which photon absorptionby a quark in one nucleon followed by its high momentum transfer interactionwith a quark of the other nucleon leads to the production of two nucleons withhigh relative momentum. We sum the relevant quark rescattering diagrams, anddemonstrate that the scattering amplitude can be expressed as a convolution ofthe large angle NN scattering amplitude, the hard photon-quark interactionvertex and the low-momentum nuclear wave function. Within this model wecalculate the cross sections and polarization observables of high energy gamma+ d --> pn and gamma + ^3He --> pp + n reactions.Comment: 8 pages Latex, 2 eps figures. Contribution to the conference  "Exclusive Processes at High Momentum Transfer", held at Jefferson Laboratory  May 15-18, 200
