Nuclear Data Sheets for A = 215

The evaluated spectroscopic data are presented for 12 known nuclides of mass 215 (Hg, Tl, Pb, Bi, Po, At, Rn, Fr, Ra, Ac, Th, Pa). For 215Hg, 215Tl, 215Pb, and 215Pa nuclei, no excited states are known. The decay characteristics of 215Hg and 215Tl are unknown. The decay scheme of 215Pb is considered as incomplete. Ordering of γ cascades in the decay of 36.9–s isomer of 215Bi and for high–spin states above 2251 keV in 215Fr are not established. High–spin excitations, including several isomeric states, are well known in 215Bi, 215Po, 215Rn, 215Fr, 215Ra, and 215Ac. No particle–transfer reaction data are available for any of the A=215 nuclei.The rms charge radii for 215Pb, 215Bi, 215Po, 215Rn, 215Fr and 215Ra have been evaluated by Daniel Abriola, from extrapolation or interpolation of available evaluated data in 2013An02 for radii of respective Z chains using formula 9 in 2004An14.This evaluation was carried out as part of ENSDD–workshop at VECC, Kolkata for Nuclear Structure and Decay Data, organized and hosted by VECC and Board of Research in Nuclear Sciences (BRNS) in Kolkata, India, November 26–29, 2012. This work supersedes the previous A = 215 evaluation (2001Br31) published by E. Browne which covered literature prior to May 2001.
