E(level): From least-squares fit to Eγ data, ΔEγ=0.2 keV assumed when not given. Reduced χ2=2.0 is somewhat larger than critical χ2=1.5. The 849.5 and 969.4 gamma rays deviate by about 3 σ values

Jπ(level): From γγ(θ) and directional polarization in 248Cm SF decay and assumption that, since fission predominately populates yrast states, the J values generally increase with excitation energy (2002Ur04). Also it is assumed that transitions of unknown multipolarity are dipole or E2; M2 is not allowed from estimated T<10 ns for levels populated in 248Cm SF decay

T1/2(level): From γ(t), T1/2<10 ns for excited states in 248Cm SF decay (2002Ur04)

M(γ): From γγ(θ) and γ(lin pol) in 248Cm SF decay, except as stated. Also comparison to RUL from a comment by 2002Ur04 in 238Cm SF decay that T1/2<10 ns for all excited states, which excludes M2 for Eγ<700 keV or so.
