N13Levels fromC12(p,p)C12

The polarization and differential cross-section data for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}\mathrm{}(p,p)\mathrm{}{}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ on and near the anomalies at $E_p=5.38,5.88, \mathrm{and} 9.13$ MeV, reported in the preceding paper, have been analyzed to obtain level parameters for the corresponding states in ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$. Assignments of ${\frac{3}{2}}^{+}$ and ${\frac{5}{2}}^{-}$, respectively, for the 5.38- and 5.88-MeV anomalies have been verified. The doublet at 9.13 MeV is assigned spins and parities of ${\frac{5}{2}}^{-}$ and ${\frac{7}{2}}^{-}$. Quantitative fits to excitation functions in the region of the doublet have been obtained with the following values in the lab system for the resonant energy, total width, and elastic width for these states: ${\frac{5}{2}}^{-}$, 9.132 MeV, 33 keV, 8.6 keV; ${\frac{7}{2}}^{-}$, 9.132 MeV, 82 keV, 67 keV. It is found that although the two resonant energies may not be exactly equal, they probably do not differ by more than 2 keV.
