| 4112 | < 3 ns % IT = ? % SF ≤ 100 | This level may comprise several levels in the second well of the nuclear potential. Deformed states in the first well of the potential (electromagnetic isomers) have not been studied. E(level): This level may comprise several levels in the second well of the nuclear potential.

1949Hy04,1949Pe04: 233U(α,3n)234Pu chem; precursor of 30-min 226Th.
1973Ja06: 233U(α,3n)234Pu. 40 mg UO2 (99.7% enriched 233U) targets were bombarded with α-particles from 35 to 55 MeV at Karlsruhe Cyclotron. α chemical separation and purification of Pu was performed. x- and γ-rays were measured with a 27 cm3 Ge(Li) detector. α spectra were obtained with a Si surface-barrier detector. Determined T1/2 from the decay analysis of 6151α and 6202α. The result was confirmed with the analysis of the K x-ray decay curve. No γ peaks that could be assigned to the decay of 234Pu were observed.
