摘要：
Projectile fission U-238 was investigated at a bombarding energy of 750 A.MeV using a Pb target. Forward emitted fragments from Zn-80 up to 155Ce were analyzed with the Fragment Separator (FRS) and unambiguously identified by their energy-loss and time-of-flight. The magnetic selection of the largest momenta acted as a trigger of the low-energy fission component. More than forty new nuclear species were identified. The related isotopic production cross-sections are presented.
