Photoactivation experiment of ¹⁹⁷Au(γ, n) performed with 9.17-MeV γ-ray from ¹³C(p, γ)¹⁴N

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.
