Nuclear Data Sheets for A=211

The evaluated spectroscopic data are presented for 11 known nuclides of mass 211 (Hg, Ti, Pb, Bi, Po, At, Rn, Fr, Ra, Ac, Th). The Pa-211 nuclide is included here but its identification remains uncertain. For Hg-211, Tl-211, Ac-211 and Th-211 nuclei, only the ground-state information is available. Their decay characteristics are mostly unknown. Fr-211 is suggested to decay partially through e decay mode, but its decay scheme remains poorly known. While high-spin excitations, including several isomers, are well studied in Pb-211, Bi-211, Po-211, At-211, Rn-211 and Fr-211, the particle-transfer data are available for only Hip and Bi-211. 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.
