Abstract

Neutron-rich lead and bismuth isotopes have been produced by cold-fragmentation reactions induced by 238U projectiles at 1AGeV impinging on a beryllium target. The high-resolving power FRagment Separator (FRS) at GSI allowed us to identify and determine the production cross-sections of 43 nuclei, nine of them for the first time (216,217,218,219Pb and 219,220,221,222,223Bi). These data are compared to other previously measured cross-sections in similar reactions and model calculations.
