We have studied the reaction of 240 MeV /sup 12/C ions with /sup 238/U targets using radiochemistry techniques. We measured the formation cross sections of 139 radioactive nuclides. We have used these data to determine the charge and mass distribution of the fission products. The mass distribution is interpreted as a superposition of two main components: (1) products from high-energy fission processes, 3480 +- 700 mb, and (2) products from low-energy fission, 1500 +- 220 mb. We also estimate the production of targetlike nuclides to be 250 +- 100 mb. The high-energy fission products can be resolved into products due to fusion-fission and fast fission, and products due to high-energy sequential fission. We have constructed the excitation functions of some product nuclides with Z-Z/sub pd/>2.
