Levels inN16from the Total Neutron Cross Section ofN15

The total neutron cross section of ${\mathrm{N}}^{15}$ has been measured for energies from 0.45 to 2.20 MeV. Neutrons with energy spreads between 15 and 30 keV were produced by the ${\mathrm{Li}}^7(p, n){\mathrm{Be}}^7$ or $\mathrm{T}(p, n){\mathrm{He}}^3$ reaction with protons from a Van de Graaff accelerator. Resonances were observed in the total cross section at laboratory energies of 0.93, 1.11, 1.57, 1.92, and 2.02 MeV with widths of 30, 20, ≤10, ≤15, and 55 keV, respectively. The excitation energies, spins, and parities for the corresponding ${\mathrm{N}}^{16}$ levels deduced from this experiment are, respectively, 3.37, $1^{+}$; 3.54, ($0^{+}$); 3.97, ($1^{-}$); 4.30, ($1^{+}$); and 4.39, $1^{-}$; where the energies are in MeV.
