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)
