Measurement of the fusion excitation function for ¹⁸O + ¹²C and ¹⁹O + ¹²C is described. The fusion cross-section is extracted through the direct measurement of evaporation residues resulting from the fusion process. At near barrier energies, the single additional neutron present in ¹⁹O results in an enhancement in the fusion cross-section by a factor of over three as compared to ¹⁸O.
