Recommended Nuclear Structure and Decay Data for A=206 Isobars

Abstract

Evaluated nuclear structure and decay data for all nuclei with mass number A=206 (²⁰⁶Pt, ²⁰⁶Au, ²⁰⁶Hg, ²⁰⁶Tl, ²⁰⁶Pb, ²⁰⁶Bi, ²⁰⁶Po, ²⁰⁶At, ²⁰⁶Rn, ²⁰⁶Fr, ²⁰⁶Ra and ²⁰⁶Ac), are presented. All available experimental data are compiled and evaluated, and best values for level and γ-ray energies, quantum numbers, lifetimes, γ-ray intensities and transition probabilities, as well as other nuclear properties, are recommended. Inconsistencies and discrepancies that exist in the literature are discussed. A number of computer codes (https://www-nds.iaea.org/public/ensdf_pgm/) developed by members of the NSDD network were used during the evaluation process. This work supersedes the earlier evaluation by F.G. Kondev (2008Ko21), published in Nuclear Data Sheets 109, 1527 (2008).
