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).

评估所有原子核的核结构和衰变数据以及质量数$A=200$（²⁰⁰ Os、²⁰⁰ Ir、²⁰⁰ Pt、²⁰⁰ Au、²⁰⁰ Hg 、 ²⁰⁰ Tl、²⁰⁰ Pb、²⁰⁰ Bi、²⁰⁰ Po、²⁰⁰ At、²⁰⁰ Rn 和²⁰⁰ Fr）。所有可用的实验数据都经过编译和评估，并推荐了能级和γ射线能量、量子数、寿命、γ射线强度和跃迁概率以及其他核特性的最佳值。讨论了文献中存在的不一致和差异。评估过程中使用了 NSDD 网络成员开发的许多计算机代码 ( https://www-nds.iaea.org/public/ensdf_pgm/ )。这项工作取代了 FG Kondev 和 S. Lalkovski (2007Ko42) 发表在Nuclear Data Sheets 108 , 1471 (2007)上的早期评估。
