Photonuclear reaction study with the (p, γ) resonance γ-source

The (p, γ ) resonance is a good way to produce monoenergetic γ rays. It becomes an important tool for studying photonuclear reactions. In this work, 13 C(p, γ )14 N resonance is studied to produce 9.17 MeV γ ray using the 2 × 1.7 MV tandem accelerator at CIAE. The flux of 9.17 MeV γ was determined to be 2.3 × 105 /s. 197 Au photoneutron cross section was measured to be 45.4 ± 6.9 mb under the irradiation of 13 C(p, γ )14 N resonance γ -source. The value is close to the previous results. It certificates that we have developed an experimental method for photonuclear reaction study.
