Experimental fission excitation functions for compound nuclei ${}_{}{}^{52}{}_{}{}^{}\mathrm{Fe}$, ${}_{}{}^{49}{}_{}{}^{}\mathrm{Cr}$, ${}_{}{}^{46}{}_{}{}^{}\mathrm{V}$, and ${}_{}{}^{44}{}_{}{}^{}\mathrm{Ti}$ formed in heavy-ion reactions are analyzed in the Hauser-Feshbach/Bohr-Wheeler formalism using fission barriers based on the rotating liquid drop model of Cohen et al. and on the rotating finite range model of Sierk. We conclude that the rotating finite range approach gives better reproduction of experimental fission yields, consistent with results found for heavier systems.
