The reaction ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}(p, \gamma ){}_{}{}^{15}{}_{}{}^{}\mathrm{O}$ was used to examine the resonance structure in ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$ between 8.8 and 9.0 MeV. The resonance previously reported at $E_p=1.742\mathrm{}$ MeV was found to have two components corresponding to excitations in ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$ of 8.920 and 8.925 MeV, respectively. The decay properties of these two levels were studied with high-resolution Ge(Li) detectors, showing that they closely resemble the properties of probable mirror levels at 9.23 and 9.155 MeV in ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$.
