Fusion-evaporation excitation functions for complete fusion of {sup 16}O with {sup 197}Au and {sup 208}Pb have been measured from the barrier up to excitation energies of about 100 MeV. Using the pulsed {sup 16}O beam from the Stony Brook LINAC, the very slow evaporation residues (ER`s) were separated in an electrostatic deflector system and identified in an array of three surface barrier detectors by their time of flight and energy. While the ER cross sections in the vicinity of the fusion barrier allow the extraction of important statistical model parameters such as fission barrier heights, data at higher excitation energies can yield insight into processes beyond the statistical model regime. The results will be discussed with respect to both aspects.
