Arenh£¿vel %J Physics %D 1994 %I arXiv %R 10.1016/0370-2693(94)91399-4 %X The cross section of the reaction $^3$He$(\gamma,pn)p_{spec}$ in the energy range 150 - 450 MeV has been calculated in a quasifree two-body model and compared with a recent kinematically complete experiment. In comparison with free deuteron disintegration the cross section is increased by a factor of about 1.5 in reasonable agreement with the data for photon energies above 200 MeV. At lower energies the data deviate from the two-body behaviour and thus suggest a more important role of the spectator requiring a more exact treatment. %U http://arxiv.org/abs/nucl-th/9405029v1
