Elastic scattering cross sections have been measured for ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ with 144 MeV protons at laboratory angles between 5° and 58°. Optical model parameters for ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ were determined from these data, and parameters for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ were determined from previously existing data at 144 MeV.

NUCLEAR REACTIONS ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}\mathrm{}(p,p)\mathrm{}{}_{}{}^{14}{}_{}{}^{}\mathrm{N}$, $E_p=144\mathrm{}$ MeV; measured $\sigma \left(\theta \right)$; optical model analysis for ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ and existing ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ data.
