摘　　要：High energy γ-ray can be used for nuclear waste transmutation by using the giant dipole resonance(GDR). The photonuclear reaction 197Au(γ, n) is known as a standard for studies on photoactivation experiments. The previous experiments on 197Au(γ, n) have been performed with bremsstrahlung, positron annihilation in flight or laser Compton scattering γ-ray.In this work, a new mono-energetic γ-ray source based on 13C(p,γ)^14N reaction is used to measure the cross section of 197Au(γ, n) and the measured value is compared with the results obtained with other ways.High energy γ-ray can be used for nuclear waste transmutation by using the giant dipole resonance（GDR）.
