Abstract：
The major purpose of the present paper is to study medium energy (γ, p) reactionmechanisms. Differential cross section calculations are performed in a picture whichincludes both direct reaction process and an excitation of △-isobar-hole states. It isshown that simple PWIA calculation can not give a good fit to the data, but the △-hresult is in reasonable agreement with experiment. This means that the role of △ in-termediate excitation in the. (γ, p) reaction is significant. Some discussions about ob-tained results are also given in the paper.
