The fusion evaporation-residue cross sections for {sup 32}S+{sup 184}W have been measured at beam energies of E{sub beam}=165, 174, 185, 196, 205, 215, 225, 236, 246, and 257 MeV using the ATLAS Fragment Mass Analyzer. The data are compared with statistical model calculations and it is found that a nuclear dissipation strength, which increases with the excitation energy, is required to reproduce the excitation function. A comparison with previously published data shows that the dissipation strength depends strongly on the shell structure of the nuclear system. thinsp {copyright} {ital 1999} {ital The American Physical Society}
