Two levels at or near 2002 keV, each deexcited by an Eγ≈647 keV transition, are proposed in (40Ca,5pnγ) to account for observed Doppler splitting of 1355γ in coin spectra gated by 394γ, 485γ, 495γ, 545γ, 622γ and 1067γ. Alternatively, an isomeric level slightly above the 2001 level may deexcite to the latter via an unobserved, highly converted low-energy transition. However, the inconsistency between 647γ(θ) in (3He,2pnγ), 647γ anisotropy in (40Ca,5pnγ) and DCO ratio in (35Cl,4p3nγ) suggests that the 647γ is indeed a doublet whose components deexcite states which have been populated to differing extents in the different reactions. The evaluator adopts this scenario, even though 1995Gh02 conclude from their (35Cl,4p3nγ) data that the 646γ is not a doublet. Jπ(level): From (40Ca,5pnγ), based on γ anisotropy and the assumptions that all observed γ’s have Ji|>Jf, most have Ji>Jf and that crossover transitions are E2, unless noted otherwise. | |

Other Reactions:
46Ti(54Fe,5p3nγ), E(54Fe)=225 MeV (1990IsZY): measured Eγ, γγ coin; searched for ns isomers; attributed a 257γ-500γ-1347γ cascade to 92Tc, implying levels at 1347, 1847 and 2104. None of these transitions has been confirmed in subsequent (40Ca,5pnγ) or (35Cl,4p3nγ) studies, and the evaluator does not adopt them as transitions in 92Tc. Furthermore, 1995Gh02 have reassigned all three transitions to 94Ru.
For shell-model calculations see, e.g., 1974Gr36, 1976Se01, 1976Gr07, 1992Si15, 1995Gh02, 1996Tu03.
Levels: The adopted level scheme is based on that of 1994Ar33 in (40Ca,5pnγ). However, the evaluator has adopted several of the modifications suggested by 1995Gh02 in (35Cl,4p3nγ): (i) the order of the 663 and 636 cascade gammas has been reversed, so the weaker γ lies higher in the cascade; (ii) the 1786γ is placed so it directly feeds the (15+) 3588 level (an alternative placement given by 1994Ar33) because 1995Gh02 suggest that a 627γ (not the 1786γ) lies immediately above the 2058γ, and the placement is shown as tentative because the 1786γ was not observed by 1995Gh02; (iii) an 1108γ-1938γ cascade is added feeding the (17-) 4787 level (as in 1995Gh02) but, owing to the strength of the 1108γ in 1995Gh02, the evaluator allows that it may be a doublet there and retains 1994Ar33’s placement of an 1108γ from the (15-) 4048 level; (iv) the 1986γ is placed feeding the (15-) 4048 level (as in 1995Gh02), instead of the (16-) 4716 level (1994Ar33); (v) addition of 1015.2γ, 1051.6γ. Additional inconsistencies between the level schemes of 1994Ar33 and 1995Gh02 center on whether there are two levels near 2002 keV and whether the 647γ is a doublet (see comment on E(2002 levels)).
Levels: See 1994Ar33, 1995Gh02, 1996Tu03 for further discussion of possible configuration assignments for 92Tc levels.
