Abstract: Large angle photodisintegration of two nucleons from the 3He nucleus isstudied within the framework of the hard rescattering model HRM. In the HRMthe incoming photon is absorbed by one nucleon-s valence quark that thenundergoes a hard rescattering reaction with a valence quark from the secondnucleon producing two nucleons emerging at large transverse momentum .Parameter free cross sections for pp and pn break up channels are calculatedthrough the input of experimental cross sections on pp and pn elasticscattering. The calculated cross section for pp breakup and its predictedenergy dependency are in good agreement with recent experimental data.Predictions on spectator momentum distributions and helicity transfer are alsopresented.
