The ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(t,{}_{}{}^3{}_{}{}^{}\mathrm{He})$ reaction at an incident energy of 23.5 MeV has been used to study the low-lying levels of ${}_{}{}^{16}{}_{}{}^{}\mathrm{N}$. A comparison of these results with a previous study of the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}({}_{}{}^3{}_{}{}^{}\mathrm{He},t){}_{}{}^{16}{}_{}{}^{}\mathrm{F}$ reaction permits assignment of $J^{\pi }=0^{-}\left(1^{-}\right),1^{-}\left(0^{-}\right),2^{-}\left(3^{-}\right),\mathrm{and}{3}^{-}\left(2^{-}\right)$ for the ground, 0.197-, 0.424-, and 0.720-MeV states of ${}_{}{}^{16}{}_{}{}^{}\mathrm{F}$, respectively.

NUCLEAR REACTIONS ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(t,{}_{}{}^3{}_{}{}^{}\mathrm{He})$, $E=23.5\mathrm{}$ MeV. ${}_{}{}^{16}{}_{}{}^{}\mathrm{N}$ levels, analog identification in ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{F}$, deduced $J^{\pi }$ in ${}_{}{}^{16}{}_{}{}^{}\mathrm{F}$.
