Evaporation residue and fission/fission-like cross sections are reported for the bombardment of /sup 62/Ni, /sup 116/Sn, and /sup 141/Pr targets with 200 and 215 MeV /sup 35/Cl ions. These data plus data previously reported at lower energies have been analyzed by a Hauser-Feshbach statistical code with Bohr-Wheeler model fission competition. The rotating liquid drop model was used to evaluate effective fission barriers. Barrier reductions of 35--45 % of the rotating liquid drop model values were required over an angular momentum range for which fission was measured, in agreement with earlier analyses. The sensitivity of results to the sharp cutoff assumption was tested and found to be unimportant over the energy ranges covered in this work.
