The possibilities for description of photonuclear reactions by the coupledchannel method are examined. It is shown that the application of an optical potential with a realistic imaginary part does not lead to the phenomenon of giant resonance in the hole channels of the final nucleus. This may indicate both a large contribution to the imaginary part of the optical potential from the simplest channels and the inapplicability in principle of the coupledchannel method with a complex optical potential for a realistic description of photonuclear reactions.
