General Comments:

The α-decay chain 202Fr - 198At - 194Bi suggests population of two 194Bi activities: 194Bi(Jπ=(3+),95 s, g.s.) and 194Bi(Jπ=(10-),115 s, 0+x level) (1992Hu04,1991Va04). α second 194Bi(Jπ=(6+,7+),125 s, 0+y level) isomer was inferred from electron-capture decay studies (1987Va09). The two isomers are now identified at 161 8 and 150 50 keV, respectively.

Other measurements:

2017Ba12 (also 2017Mo44): measurement of hyperfine spectra, magnetic dipole moments and rms radii using three-step laser resonance ionization and in-source laser spectroscopy at IRIS facility of Petersburg Nuclear Physics Institute

Mass measurement: 2013St25, 2008We02, 2005GeZW, 2000Ra23. Other: 2005We13

Levels: Band assignments are from 159Tb(40Ar,5nγ) (2020He17)

Q-value: S(2n)=18630 30, S(2p)=4730 30, Q(ε)=8185 18, Q(εp)=4165 9 (2021Wa16)

E(level): From a least-squares fit to γ-ray energies by keeping energy of the 161-keV level fixed, without its uncertainty of 8 keV, and with doubled uncertainties in Eγ values for six γ rays as indicated, resulting in reduced χ2=3.2 as compared to critical χ2=1.7. Without this adjustment, reduced χ2=5.9. It appears that the listed uncertainties in γ-ray energies are somewhat underestimated. All the level energies are relative to 161-keV level, with no uncertainty. For absolute uncertainties, 8 keV uncertainty in the 161-keV level should be considered.

Jπ(level): Assignments for high-spin levels are based on measured γγ(DCO), γ(lin pol) in 159Tb(40Ar,5nγ), band assignments and γ-decay patterns, assuming that spin values are generally in ascending order as the excitation energy increases, typical of reactions populating yrast level structures.
