Cross Sections for the ¹⁴N(n,p₀), (n,α₀), and (n,α₁) Reactions from 0.5 to 15 MeV

Cross sections have been measured for the ¹⁴N(n, p₀) reaction from 0.5 to 7.0 MeV and for the (n, α₀) and (n, α₁) reactions from 1 to 15 MeV and from 4 to 15 MeV, respectively. The data were obtained using a gaseous scintillator containing nitrogen and xenon mixtures. A Linac was used as a pulsed white neutron source with a 29-m flight path. The results of the measurement are compared to the current evaluated file for nitrogen; agreement is good for neutron energies below 8 MeV, but the measurement is substantially higher than the evaluation for neutron energies near 10 MeV.
