E(level): From least-squares fit to Eγ values, assuming 0.3 keV uncertainty for Eγ when not stated. Uncertainties of 652.28γ from 942.6 level 996.4γ from 1214.07 level were doubled to obtain an acceptable fit. Reduced χ2=1.7 as compared to critical χ2=1.3
T1/2(level): For excited states values are from 2011Ro42, measured by βγ(t) and γγ(t), fast timing technique using BaF2 and LaBr3 detectors with gating on the HPGe detector. The time spectra were analyzed by shape deconvolution method, and half-life obtained as a slope on the delayed part of the time spectrum and/or by the centroid-shift method, the latter, especially for shorter half-lives up to about 10 ps or so. 2012Ro47 conference report is from the same authors.
