[en] Experimental data pertaining to all nuclei with mass A=194 were evaluated. Level schemes from both radioactive decay and reaction studies are presented, along with associated tables of experimental data and adopted properties for levels and γ rays. The literature cutoff date for this revision is September 30, 1996. Extensive high-spin experiments using large gamma-detector arrays have revealed superdeformed structures in ¹⁹⁴Hg (three SD bands: Yrast and pair of excited signature partners). ¹⁹⁴Tl (six SD bands: Three pairs of signature partners), and ¹⁹⁴Pb (three SD bands: Yrast and pair of excited signature partners). For yrast bands (SD-1) in ¹⁹⁴Hg and ¹⁹⁴Pb, connecting transitions between the SD band and normal bands have recently been reported. Several dipole (oblate) bands in ¹⁹⁴Pb, some based on high-K (oblate) states have been reported from similar in-beam γ-ray experiments. New γγ coincidence measurements using the ¹⁹³Ir(n,γ) reaction helped to place several transitions in the level scheme and established the 31.85-ms ¹⁹⁴Ir isomer at 147.078 keV. Results from the first study of the ¹⁹³Ir(d,p) reaction agree with those from (n, γ). Unpublished γγ coincidence results (using HERA, an array of 20 intrinsic germanium detectors) revealed a new level in ¹⁹⁴Pt at 1737.4 keV. It also provided correct placement in the decay scheme for many γ rays from ¹⁹⁴Au ε decay. Recent measurements of the α-decay chain ²⁰²Fr-¹⁹⁸At-¹⁹⁴Bi confirm the existence of ¹⁹⁴Bi isomers, and show population to previously unknown levels at 218 and 396 keV in ¹⁹⁴Bi. 480 refs
