E(level): Based on adopted Eγ. Excited states are shown as uncertain because order of γ cascade in (58Ni,2nγ) could not Be established due to similarity between intensities of the transitions.
Jπ(level): From probable band structure, except as noted.
E(γ): From 192Mo(78Kr,2nγ).

0.0 | 0+ | 2.02 ms 10 % α ≈ 100 | %α: only α decay observed. Gross β decay theory (1973Ta30) predicts a partial β decay T1/2≈1 s implying %ε+%β+≈0.2. E(level): %α: only α decay observed. Gross β decay theory (1973Ta30) predicts a partial β decay T1/2≈1 s implying %ε+%β+≈0.2. Kπ=0+ GS band (2009Go16). |
