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 215 Hg, 215 Tl, 215 Pb, and 215 Pa nuclei, no excited states are known. The decay characteristics of 215 Hg and 215 Tl are unknown. The decay scheme of 215 Pb is considered as incomplete. Ordering of γ cascades in the decay of 36.9–s isomer of 215 Bi and for high–spin states above 2251 keV in 215 Fr are not established. High–spin excitations, including several isomeric states, are well known in 215 Bi, 215 Po, 215 Rn, 215 Fr, 215 Ra, and 215 Ac. No particle–transfer reaction data are available for any of the A=215 nuclei. The rms charge radii for 215 Pb, 215 Bi, 215 Po, 215 Rn, 215 Fr and 215 Ra 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.
