Fusion excitation functions of 16O+76Ge and 18O+74Ge have been measured with high precision at energies near and below the Coulomb barrier. Coupled-channels calculations including inelastic excitations well reproduce the experimental fusion excitation functions and the corresponding barrier distributions. There is no evidence that the two-neutron transfer with positive Q-value plays a role in the 18O+74Ge fusion. A systematic investigation on 18O induced fusions has been performed to understand the roles of two-neutron transfers with positive Q-values, but the effects are inconsistent. No definitive conclusion can be made at present and further studies are strongly desired.
