Fusion excitation functions for 16,17O + 144Sm have been measured to high precision. The extracted fusion barrier distributions show a double-peaked structure interpreted in terms of coupling to inelastic collective excitations of the target. The effect of the positive Q-value neutron stripping channel is evident in the reaction with 17O. Fission and evaporation residue cross-sections and excitation functions have been measured for the reaction of 16O + 208Pb and the fusion barrier distribution and fission anisotropies determined. It is found that the moments of the fusion ℓ-distribution determined from the fusion and fission measurements are in good agreement.
