123SB DG CC$FROM BrIcc v2.3a (10-Sep-2014) 2008Ki07, "Frozen Orbitals" appr.
123SB c 1974Ra03: {+123}Sn activity was produced by irradiation of 95%
123SB2c enriched {+122}Sn with thermal neutrons at ORNL. |g rays were
123SB3c detected with a 50-cm{+3} Ge(Li) detector. Measured E|g, I|g. Deduced
123SB4c levels, J, |p, |b-decay branching ratios, log {Ift}. Comparisons with
123SB5c available data.
123SB c 1966Au04: {+123}Sn activity was produced by irradiating 10 mg of
123SB2c enriched {+122}Sn metal in the ORR reactor at ORNL. |g rays were
123SB3c detected with NaI(Tl) and Ge(Li) detectors; |b particles were detected
123SB4c with a 4|p electron detector. Measured E|g, I|g, E|b, I|b, |g|g-coin,
123SB5c |b|g-coin. Deduced levels, J, |p, |b-decay branching ratios.

123SB cG E$from 40.06-min isomer decay in 1974Ra03. Other: a very weak peak of
123SB2cG 155 {I10} seen in coincidence with 1030|g in 1966Au04, with about 4% of
123SB3cG the intensity of 1030|g, making a level at 1187; but this placement
123SB4cG and the 1187 level were not confirmed in other studies and instead, the
123SB5cG 155|g could correspond to 160|g here.
