Nuclear Data Sheets for A = 210

Evaluated spectroscopic data for 210Au, 210Hg, 210Tl, 210Pb, 210Bi, 210Po, 210At, 210Rn, 210Fr, 210Ra, 210Ac, and 210Th 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 μs isomers of 210Hg by 2013Go10 and measurement of an excited level energy at 1709 keV 30 of 210Rn from 214Rn α decay: 68.6 μs 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,xnγ).
