The /sup 14/N(n,..gamma../sub 0/)/sup 15/N reaction has been studied over a neutron energy range of 5.6 MeV to 13 MeV. Data include a 90/sup 0/ 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 /sup 14/N(p,..gamma../sub 0/)/sup 15/O reaction and different from the /sup 14/C(p,..gamma../sub 0/)/sup 15/N reaction. These differences can be understood in terms of the different isospin states allowed in each reaction.
