The reaction ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}({}_{}{}^{14}{}_{}{}^{}\mathrm{N}, \alpha )$ ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ has been investigated in the energy range $8.5\le E_{\mathrm{c}.\mathrm{m}.\mathrm{}}\le 11.6$ MeV. The experimental data do not give evidence for the existence of resonances in the ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ + ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$ system.

NUCLEAR REACTIONS ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}({}_{}{}^{14}{}_{}{}^{}\mathrm{N}, \alpha )$, $E=8.5-11.6\mathrm{}$ MeV (c.m.), measured $\sigma (\theta , E)$. No resonances observed.
