E(level): From least squares fit to Eγ for levels deexcited by gammas, holding E(135 level) fixed at 135.5 4; average from cross-referenced particle reactions otherwise; note that ΔE=10 keV has been assumed for E(level) from (3He,d) but ΔE may, in fact, be as low as 5 keV.
T1/2(level): Upper limit based on experimental timing resolution from (7Li,3nγ), except as noted.

The only energetically possible transition is a seventh-forbidden branch to 0+ 92Mo(g.s.). Systematics for log ft values for such a transition have not been established, but log ft must significantly exceed 22.5, the lowest value known for a 4th forbidden decay; this would imply %Iβ<2×10-6, so this decay mode can be ignored.

Levels: The first six positive-parity levels are believed to be members of the configuration=((π 1g9/2)(ν 2d5/2)) multiplet. The positive parity of these states is determined by L=4 in (3He,d) on 5/2+ target. If 135 level has Jπ=2+ (which is very probable, given that 92Nb (10 d) ε decays to 2+ states in 92Zr, but not to 0+ or 4+ states), then the spins of 3+, 4+, 5+ states are determined uniquely from the multipolarities of γ transitions (1979Mi08). The negative-parity states (2- and 3-) at 226 and 390 keV are presumed to be members of the configuration=((π 2p1/2)(ν 2d5/2)) doublet.
Levels: Owing to the high level density, the relationship between levels from different experiments is not always determined uniquely; the evaluator’s best estimate is given here.
Levels: For theory see, e.g., 1975Gl07, 1975Mo01, 1976It01, 1978Ma10.
