E(level): From a least-squares fit to Eγ
Jπ(level): Based on multipolarity extracted in β- decay from conversion electron intensities and fast timing data (1998Gu09). The agreement between the theoretical predictions and the measured α confirm the previously tentatively assigned spins in 1982Ru04. 1982Ru04: show a comparison of experimental branching ratios with those expected from the Alaga rule as modified to account for Coriolis interaction between the Kπ=0- and the (unobserved) Kπ=1- bands. These calculated branching ratios for the E1 transitions between the Kπ=0- and Kπ=0+, Kπ=2+ bands are in good agreement with experiment
T1/2(level): From 1998Gu09 using βγγ(t) method, except otherwise noted.
E(γ): Weighted average of available data, unless noted otherwise
I(γ): Relative photon branching from each level in 228Fr β- decay.
M(γ): Extracted from the measured conversion electron intensity in 228Fr β- decay. These are in good agreement with the theoretical predictions (1998Gu09). Also 232Th(136Xe,Xγ) reaction assumes that γ-rays connecting thE in-band states of the g.s. and Kπ=0- octupole-vibrational bands are E2; and the intraband γ’s are E1
