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)
