E(level): From least-squares fit to Eγ and relative to E(7+)=35 keV 31, unless otherwise stated

M(γ): From angular distribution ratios R=Iγ(35|’)/Iγ(90|’) in (HI,xnγ) (2006Zh22) and the apparent band structures, unless otherwise stated. Values of 0.7 and 1.3 are expected for stretched (ΔJ=1) dipole and quadrupole (ΔJ=2) transitions, respectively.
