0.0 | (9/2+) | 0.28 s 3 % β- = 100 % β-n ≤ 2.0 3 | %β-n: unweighted average of 1.72 23 (1980Lu04), 1.55 7 (1986Wa17), and 2.64 13 (1993Ru01). Other: 5.5 19 (1981En05). Similarity in T1/2’s does not allow decomposition of the decay curves. From the measured fission yield ratios of E(302):E(3764):g.s.=0.82/0.014/0.16 (1993Ru01) in 235U(n,F) reaction, the evaluators estimate ≈0.3% for g.s., ≈1.6% for (1/2-) isomer and ≈0.03 for (21/2-) isomer. This branching between the g.s. and the first isomer is consistent with that in 127In and 129In. E(level): %β-n: unweighted average of 1.72 23 (1980Lu04), 1.55 7 (1986Wa17), and 2.64 13 (1993Ru01).
