123CD DG CC$FROM BrIcc v2.3a (10-Sep-2014) 2008Ki07, "Frozen Orbitals" appr.
123CD c 1989Hu10: {+123}Ag source was produced via U(n,F) with fast neutrons
123CD2c from the TANDAR accelerator. |g rays were detected with two HPGe
123CD3c detectors. Measured E|g, I|g, |g|g-coin, |g|g(t), |g(t). Deduced
123CD4c levels, J, |p, T{-1/2}, |b-decay branching ratios, log {Ift}.
123CD5c Systematics of neighboring odd-A Cd isotopes. Comparisons with
123CD6c theoretical calculations.
123CD c Other: 1989Hu03, 1986Ma42
123CD c The decay scheme is from that proposed by 1989Hu10 with the energy of
123CD2c the 11/2- isomer shifted from 316 keV to around 140 keV from a
123CD3c mass-excess measurement by 2013Ka08 and with upper levels shifted
123CD4c accordingly. Note that the energy, 316 keV, of the 11/2- isomer
123CD5c proposed by 1989Hu10 is from a search to maximize the number of shared
123CD6c levels that de-exciting to both the isomer and the ground state,
123CD7c without a direct experimental evidence. 2013Ka08 claim that the isomer
123CD8c should be at an energy of 144 keV {I4} from their direct mass
123CD9c measurement in which the g.s. and the isomer are resolved, with support
123CDac also from the energy systematics of the 11/2- states in neighboring
123CDbc odd-A Cd isotopes. 2013Ka08 further point out that many of the gating
123CDcc transitions used to deduced |b-decay Q-value of {+123}Cd g.s. by
123CDdc 1987Sp09 actually belong to the |b decay of the isomer, based on a
123CDec later study by 1989Hu03. With that being corrected, 2013Ka08 deduced
123CDfc Q-values for the g.s. and isomer |b decays from the measured end-point
123CDgc energies in 1987Sp09, resulting in an energy of 135 keV {I53} for
123CDhc the isomer that further supports their value of 144 keV {I4}.
123CD c The decay scheme should be considered as incomplete due to a large gap
123CD2c between the highest observed level and the Q-value. Total decay energy
123CD3c deposit of 7835 keV {I190} calculated by RADLIST code
123CD cB IB,LOGFT$Deduced by the evaluator from intensity balance at
123CD2cB each level. These values should be considered as approximate since
123CD3cB the level scheme seems incomplete in view of a large gap of |?5 MeV
123CD4cB between the highest (known) populated level at 2910 and
123CD5cB Q(|b{+-})=7870, allowing the possibility of a significant amount of
123CD6cB additional levels and associated unobserved transitions (pandemonium
123CD7cB effect).
123CD cG E,RI$From 1989Hu10. Placements of some |g rays are adjusted due to
123CD2cG the energy of the 11/2- isomer being shifted from 316 keV proposed in
123CD3cG 1989Hu10 to 140 keV proposed in 2013Ka08 from their direct mass
123CD4cG mass measurement.
123CD cG CC(L)$Calculated for |d=1
123CD cL E$From a least-squares fit to |g-ray energies.
123CD cL J,T$From Adopted Levels. Adopted spin-parity assignments here are
123CD2cL mostly from those proposed by 1989Hu10 based on systematics of
123CD3cL neighboring odd-A Cd isotopes.

123CD cG E$the placements of 123.67|g and 263.87|g from the same level are
123CD2cG proposed by 2013Ka08, with the 123.67|g feeding the 11/2- isomer
123CD3cG at 144 keV {I4} from their direct mass measurement. However, such
123CD4cG placement of 123.67|g results in J|p=(7/2+), thus Mult=[M2] and
123CD5cG consequently an unreasonably large B(M2)(W.u.)=56 {+17-11} greatly
123CD6cG exceeding RUL=1. This |g is placed from a 440, (9/2-) level to feed the
123CD7cG 11/2- isomer at E=316 keV proposed in 1989Hu10. It could also be
123CD8cG implied that the 123.67|g could de-excite a different level with a very
123CD9cG close energy. It is the evaluator's option that the further
123CDacG investigation is needed to firmly make the placement of the 123.67|g
123CDbcG and the level scheme as well.
