E(level): From least-squares fit to Eγ, allowing 1 keV uncertainty in all Eγ data.

Jπ(level): Tentative values suggested in (40Ca,αpnγ), based on measured transition anisotropy ratios and comparison of E(level) with energies predicted by shell-model calculations in the (p1/2, g9/2) model space (1997Ka07), except as noted.

E(γ): From (40Ca,αpnγ), except as noted; uncertainty unstated by authors. Agreement with data from (58Ni,αpnγ) is excellent.

M(γ): Based on γ anisotropy ratio in (40Ca,αpnγ), except as noted.

E(level): π=+, yrast SEQUENCE. Shell-model calculations predict a 6+ level ≈200 keV below an 8+ level (unlike 90Nb, 92Tc, and isotones 88Nb, 90Tc, where the 6+ is 100-200 keV above the 8+ and, for 90Nb, isomeric). The strongest transition (237γ) observed in (40Ca,αpnγ) is preceded by a 1036γ whose energy is comparable to 890 and 1141 for the yrast 10+ to 8+ transitions in 90Tc and 92Tc, respectively. Shell-model calculations also predict 2+ and 4+ states ≈50 keV below and above the 6+ level, respectively; consequently, the observed 6+ level might not in fact be the g.s., but in the absence of experimental evidence to the contrary, the evaluator assigns it as the g.s. here and associates the longer of the measured 92Rh halflives with it.

M(γ): From γ asymmetry in 40Ca(58Ni,αpnγ).
  1420E(γ): from 40Ca(58Ni,αpnγ).
I(γ): From 40Ca(58Ni,αpnγ).
  9744  1939E(γ): Shell-model calculations predict a 6+ level ≈200 keV below an 8+ level (unlike 90Nb, 92Tc, and isotones 88Nb, 90Tc, where the 6+ is 100-200 keV above the 8+ and, for 90Nb, isomeric). The strongest transition (237γ) observed in (40Ca,αpnγ) is preceded by a 1036γ whose energy is comparable to 890 and 1141 for the yrast 10+ to 8+ transitions in 90Tc and 92Tc, respectively. Shell-model calculations also predict 2+ and 4+ states ≈50 keV below and above the 6+ level, respectively; consequently, the observed 6+ level might not in fact be the g.s., but in the absence of experimental evidence to the contrary, the evaluator assigns it as the g.s. here and associates the longer of the measured 92Rh halflives with it.
