Measurement of Excitation Function at Zero Degree for ~(15)N(p,n)~(15)O Reaction Neutron Source

The excitation function of 15N(p,n)15O reaction at 0 degree was measured at 38 energy points using the fast neutron Time-of-Flight(TOF) spectrometer at the HI-13 Tandem Accelerator in the China Institute of Atomic Energy(CIAE).The measured data were analyzed by Monte-Carlo simulation for the corrections of neutron flux attenuation and uncertainty of the thickness of the entrance foil.Three resonance peaks were observed in this experiment in the energy range from 6.029 to 8.056 MeV,which is comparable with the DROSG-2000 evaluated data and the PTB data.However,more experimental studies are needed since the cross sections deviate with each other.
