E(level): From least squares adjustment in (n,γ) thermal, unless otherwise specified.
Jπ(level): From rotational structure. Other supporting arguments, such as γ-ray multipolarities and reduced primary γ-ray intensities from (n,γ) resonance average reactions, are given with the individual levels.

Levels: All levels populated in (n,γ) reactions (from thermal or resonance neutron capture states with Jπ=1/2+) have spins 1/2, 3/2, or 5/2. Band assignments presented here have been based on the energy systematics of Nilsson orbital configurations, and on the systematics of rotational band parameters (1978Bo12,1972Bo16,1984Ch05). Jπ assignments to levels in the second potential well of the shape isomeric ground state are supported by tentative γ-ray multipolarities (1998Ob01,1995Ob01).
Levels: Chemical shift for the 6.67-eV n-resonance was measured, Δ<r2>/<r2>=5% relative to 239U g.s. was deduced, possibly caused by lack of deformation at 4.8 MeV (neutron binding energy) (1981Se14).
