Radiochemical measurements of cross sections for 173 nuclides produced in the reaction of 538-MeV $^{56}\mathrm{Fe}$ ions with thick $^{238}\mathrm{U}$ targets were performed and the mass-yield curve determined. Seven components were resolved, corresponding to three reaction mechanisms: (1) quasielastic transfer (810 \ifmmode\pm\else\textpm\fi{} 160 mb); (2) quasifission (350 \ifmmode\pm\else\textpm\fi{} 55 mb); (3) fusion-fission (190 \ifmmode\pm\else\textpm\fi{} 30 mb). Comparison with data from other systems indicates that the fusion-fission cross section for heavy targets depends strongly on projectile mass and target- to projectile-mass ratio. |
