The authors present evaluations of the interaction of neutrons with energies between 20 and 100 MeV with oxygen and nitrogen nuclei, which follows from their previous work on carbon. Their aim is to accurately represent integrated cross sections, inclusive emission spectra, and kerma factors, in a data library that can be used in radiation transport calculations. They apply the Feshbach-Kerman-Koonin-GNASH nuclear model code, which includes Hauser-Feshbach, pre-equilibrium, and direct reaction mechanisms, and use experimental measurements to optimize the calculations. They determine total, elastic, and nonelastic cross sections; angle-energy-correlated emission spectra for light ejectiles with A {le} 4 and gamma rays; and average energy depositions. The results for charged-particle emission spectra agree well with measurements of Subramanian et al. They compare kerma factors derived from their evaluated cross sections with experimental data, providing an integral benchmarking of their work.
