${}_{}{}^{13}{}_{}{}^{}\mathrm{C}(p,\gamma ){}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ study of the 9.13-MeV state in ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$

The structure of the midget $E_p=1701\mathrm{}$ keV resonance in the ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}(p,\gamma ){}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ reaction was restudied with a high-volume Ge(Li) detector. The (82±3)% ground state ($J^{\pi }=1^{+}$, $T=0\mathrm{}$) transition with the angular distribution $W\left(\theta \right)=1+(0.48\mathrm{}\pm 0.03)P_2\left(cos\theta \right)-(0.16\mathrm{}\pm 0.03)$ $P_4\left(cos\theta \right)$ and the new (9±3)% branches to the $6.444-(J^{\pi }=3^{+},T=0)$ and 5.832-MeV ($J^{\pi }=3^{-}$, $T=0\mathrm{}$) levels along with the deduced transition strengths lead to the new assignment of $J^{\pi }=3^{+}$, $T=0\mathrm{}$ for the 9.130-MeV state.
