Abstract
Yields of 156 nuclides were measured radiochemically to delineate the mass distribution in the reaction of 605-MeV $^{84}\mathrm{Kr}$ with thick $^{238}\mathrm{U}$ targets. The yields are consistent with decomposition of the mass distribution into five components: transfer products (700\ifmmode\pm\else\textpm\fi{}120 mb), "quasi-Kr" products centered at $A\ensuremath{\approx}85$ (470\ifmmode\pm\else\textpm\fi{}70 mb) and the products from symmetric fission of their complements (420\ifmmode\pm\else\textpm\fi{}60 mb), products from low-energy fission of $Z\ensuremath{\approx}92$ nuclides (200\ifmmode\pm\else\textpm\fi{}40 mb), products from complete fusion-fission (55\ifmmode\pm\else\textpm\fi{}15 mb), and unexplained neutron-deficient yields at $A\ensuremath{\approx}195$ (\ensuremath{\sim}40 mb).
