Abstract
Projectile fission of U-238 was investigated at a bombarding energy of 750 A.MeV using Pb and Be targets. The fully stripped forward emitted fragments from Ti to Cs were analyzed with the Fragment Separator (FR S) and unambiguously identified by their energy-loss and time-of-fligh t. The magnetic selection of the largest momenta acted as a trigger of the low-energy fission component. More than a hundred new nuclear spe cies were identified including the Ni-78, for which a cross-section of 300 pb was measured.
