Abstract

|
|
|
The 9.17MeV gamma-rays from the 13C(p,γ)14N,14N(γ,γ)14N reactions were measured. The incident 9.17MeV gamma-ray was produced from the 13C(p,γ)14N reaction at Ep=1.75MeV resonance. The 1.75MeV proton beam was accelerated using the 3MV SNU-AMS Tandetron and 1.7MV KIGAM Tandem accelerators. The enriched 13C target was 121μg/cm2 self-supporting foil, and we used liquid nitrogen as a resonant absorption target. We used a HP-Ge detector with 30% efficiency and less 2keV energy resolution. We developed new method to detect the scattered 9.17MeV gamma-ray from the nitrogen target by using the energy difference between the Doppler shifted gamma-ray from the 13C(p,γ)14N reaction and the resonant absorbed and rescattered gamma-ray from the 14N(γ,γ)14N reaction.
