Systematic experimental survey on projectile fragmentation and fission induced in collisions of238U at 1A GeV with lead

Abstract

Projectile fragmentation and fission, induced in collisions of238U at 1A GeV with lead, have systematically been studied. A complete survey on the isotopic production cross-sections of all elements between vanadium (Z = 23) and rhenium (Z = 75) is given. About 900 reaction products were identified in the GSI fragment separator FRS from magnetic rigidities, time-of-flight values, and the energy loss in a ionisation chamber. In addition, the momentum distributions of all these reaction products have been mapped, and the products are unambiguously attributed to the different reaction mechanisms due to their kinematical properties. The results are compared with empirical systematics and previous data.
