The evaluated experimental data are presented and evaluated for 15 known nuclides of mass 190 (Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi, Po). This work supersedes earlier full evaluations of A=190 by 2003Si05, 1990Si09, 1982Le22 and 1973Sc42. For ¹⁹⁰Hf, only the isotopic identification has been made, with no information about the half-life of the ground state or its decay properties. For ¹⁹⁰Ta, only one excited state as an isomer has been identified, but with no knowledge about its decay properties. For ¹⁹⁰W, ¹⁹⁰Re, ¹⁹⁰Bi and ¹⁹⁰Po, available spectroscopic data are scarce. The decay schemes of ¹⁹⁰Ta, ¹⁹⁰W, ¹⁹⁰Au, ¹⁹⁰Hg, ¹⁹⁰Au isomer decay, ¹⁹⁰Tl (both the activities), ¹⁹⁰Pb, and ¹⁹⁰Bi (both the activities) are considered incomplete by the evaluators. At present, extensive level structures, both the low-spin and high-spin, are known for ¹⁹⁰Os, ¹⁹⁰Ir, ¹⁹⁰Pt, ¹⁹⁰Au, ¹⁹⁰Hg, ¹⁹⁰Tl and ¹⁹⁰Pb, but data for level lifetimes, and γ-ray transition probabilities are generally lacking.

呈现并评估了质量为190的15种已知核素（Hf，Ta，W，Re，Os，Ir，Pt，Au，Hg，Tl，Pb，Bi，Po）的评估实验数据。这项工作取代了2003Si05、1990Si09、1982Le22和1973Sc42之前对A = 190的完整评估。对于¹⁹⁰ Hf，仅进行了同位素鉴定，没有关于基态的半衰期或其衰变特性的信息。对于¹⁹⁰ Ta，仅鉴定出一种作为异构体的激发态，但对其衰变特性一无所知。对于¹⁹⁰ W，¹⁹⁰ Re，¹⁹⁰ Bi和¹⁹⁰ Po，可用的光谱数据很少。¹⁹⁰ Ta，¹⁹⁰ W，¹⁹⁰的衰减方案评估人员认为Au，¹⁹⁰ Hg，¹⁹⁰ Au异构体衰变，¹⁹⁰ Tl（均为活性），¹⁹⁰ Pb和¹⁹⁰ Bi（均为活性）不完整。目前，广泛级结构，无论是低自旋和高自旋，已知用于^190级的OS，¹⁹⁰的Ir，¹⁹⁰的Pt，¹⁹⁰的Au，¹⁹⁰汞，¹⁹⁰ T1和¹⁹⁰的Pb，但数据为水平的寿命，和γ -通常缺少射线过渡概率。
