Evaluated nuclear structure and decay data are presented for 16 known A=126 nuclides (Rh, Pd, Ag, Cd, In, Sn, Sb, Te, I, Xe, Cs, Ba, La, Ce, Pr, Nd). The A=126 mass chain was last evaluated by J. Katakura and K. Kitao, which was published in Nuclear Data Sheets 97, 765 (2002) (2002Ka66). In 2015, B. Singh evaluated the data of ¹²⁶Rh, ¹²⁶Pd and ¹²⁶Ag. The current work is an update of these previous evaluations. Experimental data from new publications since 2002Ka66 have been incorporated. Even when no new publications appeared, some previous datasets have been modified for new β-decay Q values and conversion coefficients. Adopted values for levels and gammas are based on data of various decays and reactions. Inconsistencies and discrepancies have been noted.

提供了 16 种已知 A=126 核素（Rh、Pd、Ag、Cd、In、Sn、Sb、Te、I、Xe、Cs、Ba、La、Ce、Pr、Nd）的评估核结构和衰变数据。A=126 质量链最后由 J. Katakura 和 K. Kitao 评估，发表在核数据表 97、765 (2002) (2002Ka66) 上。2015 年，B. Singh 评估了¹²⁶ Rh、¹²⁶ Pd 和¹²⁶ Ag 的数据。当前的工作是对这些先前评估的更新。自 2002Ka66 以来新出版物的实验数据已被纳入。即使没有新的出版物出现，一些以前的数据集也已针对新的β进行了修改-衰减Q值和转换系数。采用的能级和伽马值基于各种衰变和反应的数据。已注意到不一致和差异。
