Abstract:
The N14(n,0)N15 reaction has been studied over a neutron energy range of 5.6 MeV to 13 MeV. Data include a 90° excitation function measured in 200 keV steps, and seven angular distributions. The angular distribution data show good agreement with the results of a phenomenological direct semidirect model calculation. No non-E1 radiation is required to account for these data. The cross section as a function of energy is similar to the N14(p,0)O15 reaction and different from the C14(p,0)N15 reaction. These differences can be understood in terms of the different isospin states allowed in each reaction. NUCLEAR REACTIONS N14(n,0)N15, measured (E,) from En=5.6-13.0 MeV, DSD model calculations, results compared to C14(p,0)N15 and N14(p,0)015. © 1982 The American Physical Society.
