Description

Projectile fission of 238U was investigated at a bombarding energy of 750 AMeV using a Pb target. Forward emitted fragments from 80Zn 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 low energy fission component. More than forty new nuclear species were identified. The related isotopic production cross-sections are presented. (authors). 13 refs., 4 figs., 1 tab
