ResumoA variety of nuclear reactions at energies close to the Coulomb barrier are used to populate residual nuclei in order to study their structure through methods such as γ-ray spectroscopy. The most common of these is the fusion-evaporation reaction. Recent detailed studies of heavy-ion fusion have shown how this reaction proceeds not through a single Coulomb barrier but through a distribution of barriers whose properties are intimately related to the collective modes of the target and projectile. This paper will explore possible ways of exploiting structure effects in the entrance channel to populate systems of interest in the compound nucleus and its evaporation residues. This leads to a complementarity of charged-particle and γ-ray work. Some comments will also be made on the complementarity of experiments with stable and exotic beams in the same energy region.
