The recently reported differences in the analog reactions ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(p,{}_{}{}^3{}_{}{}^{}\mathrm{He}){}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ (2.31 MeV) and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(p,t){}_{}{}^{14}{}_{}{}^{}\mathrm{O}$ (g.s.) are correctly predicted by distorted-wave Born-approximation calculations, using standard parameters with no adjustments.

NUCLEAR REACTIONS ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(p,t)$ and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(p,{}_{}{}^3{}_{}{}^{}\mathrm{He})$, $E=27\mathrm{}$ MeV; calculated $\sigma \left(\theta \right)$, ratio.
