Evaluated nuclear structure and decay data for all nuclei with mass number A=203 (²⁰³Os, ²⁰³Ir, ²⁰³Pt, ²⁰³Au, ²⁰³Hg, ²⁰³Tl, ²⁰³Pb, ²⁰³Bi, ²⁰³Po, ²⁰³At, ²⁰³Rn, ²⁰³Fr, ²⁰³Ra) 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/index.htm) developed by members of the NSDD network were used during the evaluation process. For example, the reported absolute γ-ray emission probabilities and their uncertainties were determined using the GABS code. The γ-ray transition probabilities were determined using the RULER code and the corresponding uncertainties were estimated by means of a Monte-Carlo approach. This work supersedes the earlier evaluation by F.G. Kondev (2005Ko20), published in Nuclear Data Sheets 105, 1 (2005).

评价核结构和衰变数据与质量数A的所有核= 203（^203级的OS，²⁰³的Ir，²⁰³的Pt，²⁰³的Au，²⁰³汞，²⁰³ T1中，²⁰³的Pb，²⁰³铋，²⁰³宝，²⁰³在，²⁰³ Rn，则²⁰³ Fr, ²⁰³ Ra)。所有可用的实验数据都经过编译和评估，以及能级和γ射线能量、量子数、寿命、γ 的最佳值推荐使用 - 射线强度和跃迁概率以及其他核特性。讨论了文献中存在的不一致和差异。在评估过程中使用了一些由 NSDD 网络成员开发的计算机代码（https://www-nds.iaea.org/public/ensdf_pgm/index.htm）。例如，报告的绝对γ射线发射概率及其不确定性是使用 GABS 代码确定的。的γ使用标尺代码确定射线转变概率和相应的不确定性是由一个蒙特卡洛方法的手段来估计。这项工作取代了 FG Kondev (2005Ko20) 在核数据表 105, 1 (2005) 中发表的早期评估。
