Capture and Elastic Scattering of Protons byC14

The reactions ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}(p,\gamma ){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ and ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}\mathrm{}(p,p)\mathrm{}{}_{}{}^{14}{}_{}{}^{}\mathrm{C}$ have been studied in the energy region $0.6<\mathrm{}{E}_p<2.7\mathrm{}$ MeV. Particular attention was directed to a level which is produced at $E_p=2.49\mathrm{}$ MeV ($E_x=12.54\mathrm{}$ MeV); this level is distinct from a frequently observed level at $E_x=12.51\mathrm{}$ MeV. It is concluded on the basis of a dispersion-theory fit to the scattering data that the 12.54-MeV level has $T=\frac{3}{2}$, $J={\frac{5}{2}}^{+}$, and that it is the analog of the first excited state in ${}_{}{}^{15}{}_{}{}^{}\mathrm{C}$.
