Recommended Nuclear Structure and Decay Data for A = 200 Isobars

Evaluated nuclear structure and decay data for all nuclei with mass number $A=200$ (²⁰⁰Os, ²⁰⁰Ir, ²⁰⁰Pt, ²⁰⁰Au, ²⁰⁰Hg, ²⁰⁰Tl, ²⁰⁰Pb, ²⁰⁰Bi, ²⁰⁰Po, ²⁰⁰At, ²⁰⁰Rn, and ²⁰⁰Fr), 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 and S. Lalkovski (2007Ko42), published in Nuclear Data Sheets 108, 1471 (2007).
