Giant-Dipole-Resonance Region ofN15Observed viaC14(p, p)C14Cross Section and Polarization Measurements

Cross sections and polarizations have been measured for ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}(p, p){}_{}{}^{14}{}_{}{}^{}\mathrm{C}$ scattering over the energy range corresponding to the giant-dipole-resonance region of ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$. The results indicate a $J^{\pi }={\frac{3}{2}}^{+}$ resonance of about $\Gamma =4\mathrm{}$ MeV near $Ep=10\mathrm{}$ MeV. This resonance appears to be the giant dipole resonance observed in ($p, \gamma$) measurements.
