摘要
High energy γ-rays can be used in many fields, such as nuclear waste transmutation, flash photographics, and astrophysics. The13 C(p, γ)14 N resonance reaction was used to generate high energy and mono-energetic γ-rays in this work. The thick-target yield of the 9.17-MeV γ-ray from the resonance in this reaction was determined to be(4.7±0.4)×10-9γ/proton,which was measured by a HPGe detector. Meanwhile, the angular distribution of 9.17-MeV γ-ray was also determined.The absolute efficiency of HPGe detector was calibrated using56 Co and152 Eu sources with known radioactive activities and calculated by GEANT4 simulation.
