It is found that the statistical model accounts rather well for the absolute cross sections measured recently for the reaction ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$, ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$)${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}\sim 24 \mathrm{and} \sim 36$ MeV and for the integrated ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$ yields observed in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ reaction at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=16-28\mathrm{}$ MeV. These results demonstrate that compound-nucleus formation followed by the emission of complex particles such as ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ or ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$ occurs with sizable cross sections in these reactions.
