E(level): From least-squares fit to Eγ allowing 1 keV uncertainty in all Eγ data. Uncertainties are provided by authors for no Eγ data.
Jπ(level): Values given without further comment are those proposed by 2011Li34 in 252Cf SF decay based largely on regional systematics.
M(γ): From γγ(θ) in 248Cm SF decay.

1356.4 | E(level): From 252Cf SF decay. Jπ(level): In heavier even-even n=56 isotones, the lowest-energy excited 0+ levels lie at 1682, 1582 and 1130, respectively, in Sr, Zr and Ru; 3- levels lie at 1926, 1897, 2018 and 2167, respectively, in Sr, Zr, Mo and Ru isotones. Among the 92Kr levels with unknown Jπ, the energy of the observed 1356 level most closely matches that expected for the 0+ state. The energies of the 1985, 1994, 2019, 2047, 2077 and 2164 levels, none of which has a known γ feeding a 0+ level, make them candidates for the expected 3- state. | ||
