General Comments:

Levels: 7.9 s 6 isomer found by 1988TuZY was not confirmed by 1989Gi06 and 2001BeZY

Gammas: γ-ray multipolarities determined by DCO ratio measurements found of the ΔJ=2, Q type (2004Me25 in 92Mo(54Fe,αpγ) give no supporting evidence)

Q-value: ΔQ(β-)=320 (syst,2021Wa16)

Q-value: S(2n)=22550 320 (syst), S(2p)=3720 110, Q(εp)=5160 120 (2021Wa16)

E(level): From 92Mo(54Fe,3p2nγ) for the first three excited levels of the rotational band and from 92Mo(54Fe,αpγ) for the upper levels

Jπ(level): For excited states based on syst for J=11/2- aligned bands and γ-ray multipolarities

E(γ): Eγ values given with decimal point are from (92Mo,3p2nγ) and those without decimal point are from (54Fe,αpγ)
