Neutron-induced fission cross-section ratios {sup nat}Pb/{sup 209}Bi, {sup 208}Pb/{sup 209}Bi, {sup 197}Au/{sup 209}Bi, {sup nat}W/{sup 209}Bi, {sup 181}Ta/{sup 209}Bi, and {sup 209}Bi/{sup 238}U have been measured in the 30-180 MeV energy range using the neutron beam facility at The Svedberg Laboratory in Uppsala. The {sup 7}Li(p,n) reaction was employed as a neutron source. The fission fragments were detected by thin-film breakdown counters. Cross sections at specific energies were determined using unfolding techniques with respect to the excitation function and the neutron spectra, the latter obtained from recent measurements and an evaluation. The absolute fission cross sections were obtained using the standard {sup 238}U(n,f) cross section. The {sup nat}W(n,f) and {sup 181}Ta(n,f) cross sections have been measured for the first time. The results for {sup 209}Bi(n,f), {sup nat}Pb(n,f), {sup 208}Pb(n,f), and {sup 197}Au(n,f) cross sections have been compared with available literature data. A universal easy-to-use parametrization has been suggested for all measured cross sections. The common features of subactinide neutron-induced fission cross sections are found to be similar to those of the proton-induced fission data.
