Abstract

Evaluated nuclear structure and decay data for all nuclei with mass number A=205 (Ir,Pt,Au,Hg,Tl,Pb,Bi, Po,At,Rn,Fr,Ra,Ac) are presented. The experimental data are compiled and evaluated, and best values for level and gamma-ray energies, quantum numbers, lifetimes, γ-ray intensities and transition probabilities, and other nuclear properties are recommended. The reported absolute γ-ray emission probabilities in various decay data sets were calculated using the GABS code (https://www-nds.iaea.org/public/ensdf_pgm/index.htm). Inconsistencies and discrepancies that exist in the literature are discussed. This work supersedes the earlier evaluation by F.G. Kondev (2004Ko28), published in Nuclear Data Sheets 101, 521 (2004).
