Using a proportional counter, measurements were made of the fission fragment angular distributions, kinetic energy spectra, and the total fission cross sections for the reactions C + Au, O + Au, C + Bi, and O + Bi at 16.5 Mev per nucleon bombarding energies and for the C + Bi reaction at energies from 72 to 126 Mev. The results showed the idnetic energy spectra to be independent of the excitation of the compound system and the most probable fragment kinetic energies to be 75 plus or minus 3 and 81 plus or minus 3 Mev for the gold and bismuth target reactions, respectively. In all cases the fission cross sections were found to be only 60 to 80% of the estimated compound-nucleus formation cross sections. The angular distributions were fitted by the theory of Halpern and Strutinski, and an attempt was made to determine some of the qualitative features of these heavy-ion reactions. (auth)
