Large collision residues and nuclear fission in the interaction of 25. 2-GeV /sup 12/C with uranium
Target-residue mass and charge distributions have been measured for 76 products of the interaction of 25.2-GeV /sup 12/C with U. The mass yield curve shows two prominent bumps: one for 80 < or = A < or = 145, resulting from the modest excitation-energy (50--100 MeV) fission of a species with A approx. 225, and the second for 160 < or = A < or = 190, apparently due to the survivors of a more central collision between projectile and target.
