Nuclear Data Sheets for A = 210

Abstract Evaluated spectroscopic data for 210 Au, 210 Hg, 210 Tl, 210 Pb, 210 Bi, 210 Po, 210 At, 210 Rn, 210 Fr, 210 Ra, 210 Ac, and 210 Th and corresponding level schemes from radioactive decay and reaction studies are presented. This evaluation supersedes the previous evaluation by E. Browne (2003Br13). Highlights of this publication are the identification of new μ s isomers of 210 Hg by 2013Go10 and measurement of an excited level energy at 1709 keV 30 of 210 Rn from 214 Rn α decay: 68.6 μ s by 2006Ku26 denoted as x+1664.6 in the Adopted Levels. Earlier experimental limits for x≤50 keV was proposed in 1979Po19 and 1982Po03 – (HI,xn γ ).
