The exchange-current effects in the photodisintegration of the deuteron at high energies are discussed. Special consideration is given to correlation of the exchange effects with the large direct E1 transition, whose behavior has been the object of the recent several investigations; consequences of gage invariance for the electric transitions due to exchange effects; and evaluation of the magnetic transition caused by the (33)-resonance in terms of the results of the Chew-Low theory. It is shown that exchange effects affect the electric dipole transition operator in a way consistent with the Siegert theorem. The resulting change in the electric dipole cross section is evaluated in the adiabatic approximation as well as in neglect of higher order retardation effect. It is appreciable orly at photon energies above the pion threshold. Some characteristics of the (33)-resonance effect are revealed, although nucleon recoil effects and uncertainty of nuclear force make it difficult to give any quantitative estimation. Finally the results obtained here are compared with experiment. (auth)
