98AG c 1992Pl01: {+98}Cd source was produced by spallation of a natural tin
98AG2c target with 600 MeV protons from the ISOLDE facility. Conversion
98AG3c electrons were detected with a mini-orange electron spectrometer and
98AG4c |g and X rays were detected with Ge detectors. Measured E|g, I|g,
98AG5c |g|g-coin, |gX-coin, |g(t), E(ce), I(ce), (ce)|g-coin. Deduced levels,
98AG6c J, |p, parent T{-1/2}, decay branching ratios, log{Ift}. Comparisons
98AG7c with theoretical calculations.
98AG c 2017Pa35: activity of {+98}Cd was produced via {+9}Be({+124}Xe,X|g).
98AG2c 107, 61 and 347 gamma rays were seen, and the ordering of the 107-61|g
98AG3c cascade was re-investigated and reversed from the one proposed by
98AG4c 1992Pl01.
98AG c 2019Lu08: from |b(1176|g)-coin, measured Q(|b{++} value=2.79 MeV {I8}
98AG2c to 1691 level in {+98}Ag from {+98}Cd |e decay
98AG c Other: 1978El09
98AG dG $Theoretical b-strength functions and log| {Ift} values:
98AG2dG 1993Sk03, 1991Jo10, 1988Do04, 1988Su16
98AG c Due to a large gap between Q(|b{+-})value and excitation energy of the
98AG2c highest observed level (possible pandemonium effect), the decay scheme
98AG3c could be incomplete and the deduced decay branching ratios and log{Ift}
98AG4c values could be considered as approximated.
98AG cE TI$Deduced by evaluators from I(|g+ce) intensity imbalance at each
98AG2cE level
98AG cG E,RI$From 1992Pl01, unless otherwise noted. Quoted values of
98AG2cG intensities from 1992Pl01 are the original values divided by a factor
98AG3cG of 10.
98AG cG E(X)$The ordering of 107|g and 61|g is from 2017Pa35, based on the
98AG2cG non-observation of 61|g in their time-delayed spectrum. 1992Pl01 had
98AG3cG proposed a reversed ordering, defining the intermediate level at
98AG4cG 60.55 keV, instead of the present 107 keV. Note that the ordering by
98AG5cG 1992Pl01 is based on |g|g-coin spectra accumulated for 26 hours.
98AG cG E(A)$Observed only in |g|g-coin with summed spectra for gates on 61|g,
98AG2cG 107|g, 347|g and also in coincidence with Ag K X rays (1992Pl01)
98AG cG M,MR$From I(ce)/I|g relative to those for 59|g, 97|g, 98|g, 111|g,
98AG2cG 116|g, 125|g and 140|g from {+101}Cd, {+102}Cd and {+103}Cd, unless
98AG3cG otherwise noted. The same values are adopted in Adopted Gammas.
98AG cL E$From a least-squares fit to |g-ray energies
98AG cL J,T$From Adopted Levels
98CD P 0.0 0+ 9.3 S 1 5430 40
98CD cP T$From {+98}Cd Adopted Levels
98CD cP QP$From 2017Wa10
98AG N 0.781 21 1.00
98AG cN NR$From I(|g+ce to 168 level)=100, assuming 33% uncertainty in I|g if
98AG2cN not given. %|ep<0.025 for {+98}Cd decay from Adopted Levels of {+98}Cd.
98AG3cN Due to possible pandemonium effect, the decay scheme could be
98AG4cN incomplete and thus the normalization could be considered as
98AG5cN approximated.

98AG3cG resulting in a total (|g+ce) intensity much greater than that of 107|g,
98AG4cG which is expected to be equal.
