Inclusive cross sections for the /sup 16/O+/sup 40/Ca reaction leading to fission-like fragments with mass 20less than or equal toA/sub fragment/less than or equal to28, and for the /sup 16/O+/sup 44/Ca reaction with 20less than or equal toA/sub fragment/less than or equal to30, have been determined by measurements at seven energies with 69.3less than or equal toE/sub lab/( /sup 16/O)less than or equal to87.3 MeV and for 30/sup 0/less than or equal totheta/sub lab/less than or equal to60/sup 0/. The evaporation-residue cross sections were also measured over a limited angular range at the same energies to search for any gross difference between these cross sections for the two systems. No difference was detected outside the experimental uncertainties. The resulting energy spectra and mass distributions for the fission-like yields are shown to be consistent with a fusion-fission reaction mechanism. Although it was not possible to determine the total fission-like cross sections since the apparent mass range of the fission-like yields was greater than that covered by the experiment, the magnitude and energy dependence of the observed fission-like cross sections, as compared to the evaporation-residue cross sections, are also found to be consistent with a fusion-fission mechanism.
