ABSTRACT Neutron-rich lead and bismuth isotopes have been produced by cold-fragmentation reactions induced by 238U projectiles at 1A GeV 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.

    ABSTRACT: Currently, forty-two thallium, forty-two lead, forty-one bismuth, and forty-two polonium isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.

    ABSTRACT: Currently about 3000 different nuclei are known with about another 3000-4000 predicted to exist. A review of the discovery of the nuclei, the present status and the possibilities for future discoveries are presented.

    ABSTRACT: The evaluated spectroscopic data are presented for 11 known nuclides of mass 211 (Hg, Tl, Pb, Bi, Po, At, Rn, Fr, Ra, Ac, Th). The 211Pa nuclide is included here but its identification remains uncertain. For 211Hg, 211Tl, 211Ac and 211Th nuclei, only the ground-state information is available. Their decay characteristics are mostly unknown. 211Fr is suggested to decay partially through ɛ decay mode, but its decay scheme remains poorly known. While high-spin excitations, including several isomers, are well studied in 211Pb, 211Bi, 211Po, 211At, 211Rn and 211Fr, the particle-transfer data are available for only 211Po and 211Bi.This evaluation was carried out as part of joint IAEA-ICTP workshop for Nuclear Structure and Decay Data, organized and hosted by the IAEA, Vienna and ICTP, Trieste, August 6-17, 2012. This work supersedes previous A=211 evaluation (2004Br45) published by E. Browne which covered literature before January 2003.
