The ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}(p, {\alpha }_0){}_{}{}^{11}{}_{}{}^{}\mathrm{B}$ cross sections are presented for $4 \mathrm{MeV}<E_p<7.5\mathrm{} \mathrm{MeV}$. Probable spin assignments based on Legendre polynomial fits to the measured angular distributions are given and compared to the ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}(p, p){}_{}{}^{14}{}_{}{}^{}\mathrm{C}$ results.

NUCLEAR REACTIONS ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}(p, \alpha ){}_{}{}^{11}{}_{}{}^{}\mathrm{B}$; measured $\sigma \left(\theta \right)$, $E=4.0-7.5\mathrm{}$ MeV. Probable spin assignments deduced for ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ levels. Compared results with those from ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}(p, p){}_{}{}^{14}{}_{}{}^{}\mathrm{C}$ experiment.
