Cross sections for photo-reactions of Al^<27>, C^<12> and Cu were measured by the activation method in the γ-ray energy range from 150 MeV to 720 MeV. The integrated cross sections for the reactions Al^<27> (γ,π^+) Mg^<27>, Al^<27> → Na^<24>, Al^<27> → F^<18>, and C^<12> → C^<11> in the energy region between 200 MeV and 400 MeV were 2.2x1O^<-26> cm^2 ・ MeV, 6.2x10^<-26> cm^2 ・ MeV, 2.4 x 1O^<-26> cm^2 ・ MeV, and 2.O×10^<-25> cm^2 ・ MeV, respectively. These values seem to be plausible ones from the point of view of the pion photo-production, the non-mesonic dipole absorption of photons, and the reabsorption of the pion in the nucleus. The excitation curves for the reactions Al^<27> (γ,π^+) Mg^<27> and Al^<27> → Na^<24> show that the (3/2, 3/2) resonance state of a nucleon has an appreciable effect on these reactions, however, the resonances appear to be broadened probably due to the momemtum distributions of nucleons in the nucleus.
