The fusion cross sections for the $^{10}\mathrm{B}$ + $^{16}\mathrm{O}$ and $^{12}\mathrm{C}$ + $^{14}\mathrm{N}$ systems are compared for bombarding energies up to 18 MeV/nucleon. The energy spectra, angular distributions, and relative yields of the evaporation residues are analyzed in terms of simple kinematic considerations and Hauser-Feshbach calculations. Simultaneous determinations of mass, charge, and energy and two particle coincidence measurements at ${E}_{{14}_{\mathrm{N}}}=13$ MeV/nucleon support the identification of evaporation residues based on inclusive measurements of $Z$ and $E$ alone. The gross characteristics of the residues are consistent with the main process being complete fusion followed by equilibrium decay. The excitation functions of the $^{10}\mathrm{B}$ + $^{16}\mathrm{O}$ and $^{12}\mathrm{C}$ + $^{14}\mathrm{N}$ systems show significant differences which cannot be explained in terms of simple macroscopic models. At the highest bombarding energies the fusion cross sections decrease as $\frac{1}{{E}_{\mathrm{c}.\mathrm{m}.}}$ for both systems and are consistent with a maximum angular momentum limit of $\ensuremath{\sim}27\ensuremath{\hbar}$. |
