Two integral experiments of neutron scattering and gamma-ray production from nitrogen samples performed at Intelcom Radiation Technology and Oak Ridge National Laboratory were analyzed with Monte Carlo calculations. The experimental results include angular-dependent NE-213 detector count rates for both scattered neutrons and gamma-ray production from a spherical dewar of liquid nitrogen pulsed with a neutron beam with energies from 1 to 20 MeV. Additional results were reported in the ORNL experiments for unfolded scattered neutron and gamma-ray production spectra as a function of detector angle in broad incident neutron energy bins. Multigroup Monte Carlo calculations were made to analyze all the reported results. Conclusions were drawn about the status of the ENDF/B- IV nitrogen cross-section data file from the comparison of calculated and experimental results. 1 table, 44 figures. (auth)
