155EU c The decay scheme is due primarily to 1969Un01 conbined with 2005Ra33.
155EU c 1969Un01: source produced in {+154}Sm(n,|g). Measured E|g, I|g,
155EUxc |g|g-coincidence, T{-1/2} using Ge(Li), Si(Li) and NaI detectors.
155EU c 2005Ra33: source produced in {+154}Sm(n,|g). Measured E|g, I|g,
155EUxc |g|g-coincidence, deduced log| {Ift} values. Used angular correlation
155EUxc results from 2004Ge20
155EU c There is a general good agreement in between 1969Un01 (and earlier
155EUxc studies) and 2005Ra33. The differences are noted in the text.
155EU c Other measurements: 2004Ge20, 1974BeYP, 1971Be23, 1970Re08, 1969BoZO,
155EU2c 1968Wi12, 1968Ma15, 1967Wi12, 1967Wi11, 1966Fu11, 1965Ma24, 1965Fu13,
155EU4c 1963Kr04, 1961Ve04, 1960Su03, 1959Sc37, 1950Wi07, 1942Ku03.
155EU cG $2005Ra33 give very small I{-|g} uncertainties that most likely seem
155EU2cG to not completely include the uncertainties of the efficiency
155EU2cG calibration procedure (mentioned without descriptive details), which
155EU2cG implies that the weighted average values are dominated by their values,
155EU2cG with small uncertainties. For these reasons the log| {Ift} values are
155EU2cG rounded off and listed without uncertainties (see |b{+-} radiations
155EU2cG table)
155EU cG I(K| x ray)/I(104|g)=0.229 {I10}. Weighted average of:
155EU2cG 0.236 {I24} (1969Un01); 0.230 {I16} (1969BoZO semi); 0.225 {I16}
155EUxcG (1969BoZO scin).
155EU cG $The very precise values for E|g's given by 2005Ra33
155EU2cG (much more precise than those
155EU2cG measured very precisely with curved-crystal spectrometer (from
155EU2cG 1970Re08, marked in the text)) were not adopted here (exceptions are
155EU2cG noted separately). Unless special
155EU2cG developments or precautions were taken (not mentioned by 2005Ra33),
155EU2cG HPGe detectors are not usually trusted to such precision
155EU cG E Unless otherwise noted, the listed values are those of
155EUxcG 1969Un01
155EU cG RI Unless otherwise noted, the listed values represent
155EU2cG averages of the measurements of 1966Fu11, 1967Ag05, 1968Wi12,
155EU3cG 1969BoZO, 1969Un01, and 2005Ra33 normalized to I|g(245|g)=100. For the
155EU4cG stronger transitions (I|g>5), these are weighted averages. For the
155EU5cG weaker ones, the averages are unweighted, with the listed uncertainties
155EU6cG being typical of those reported by the various authors. The
155EU7cG published uncertainties in 1967Ag05 seem quite small compared with
155EU8cG those given in the other, and later, works included here, as well as
155EU9cG comparable contemporary studies. Consequently, the evaluator has
155EUKcG increased them in a number of instances to make them more nearly
155EUScG equal to those of the other I|g values being averaged. The I|g values
155EUNcG of 1969Un01 have uncertainties ranging from 10% for strong transitions
155EUJcG to 25% for weak transitions.
155EU cG M,MR$Shown in the table are the adopted values (from Adopted Levels,
155EU3cG Gammas dataset). Values deduced in this dataset are shown in commets
155EU cG M$Values deduced in this dataset are deduced from comparison of
155EU2cG |a(K)exp, |a(L)exp, and ce ratios measured by 1968Wi12 with theoretical
155EU2cG values. The normalization of the |g-ray and ce intensities was done (by
155EU4cG 1968Wi12) by requiring that |a(L1)exp(104.3|g)=0.024 for this E1
155EU5cG transition. Although this value differs from |a(L1)=0.022 as given by
155EU6cG 1968Ha53 (whose values are employed in this evaluation), the
155EU7cG conclusions drawn here are not materially affected by this difference
155EUxcG in |a(L1) values.
155EU cG MR$Values deduced in this dataset are calculated by the evaluator from
155EU2cG the L-subshell ratio data of 1968Wi12 unless noted otherwise.
