The analysis of excitation curves and angular correlations of the $\gamma$ rays from the ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}(p, \gamma ){}_{}{}^{15}{}_{}{}^{}\mathrm{O}$ reaction confirms the existence of a doublet at 8.92 MeV in ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$. $J^{\pi }={\frac{1}{2}}^{+}$ and $J^{\pi }={\frac{1}{2}}^{-}$ assignments are determined for the spins and parities of the two members of this doublet. The 8.98 MeV level is found to have $J^{\pi }={\frac{3}{2}}^{-}$. This study was performed using a differentially pumped gas target of natural nitrogen. A comparison with ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ levels and with theoretical results is discussed.

NUCLEAR REACTIONS ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}(p, \gamma )$, $E=1.742, 1806$ MeV. Measured $\sigma \mathrm{}\left(E\right)\mathrm{}$, $\gamma \gamma \left(\theta \right)$. ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$ levels deduced $J$, $\pi$. Natural gas target.
