| 0.0 | (7-) | 0.200 s 2 % β- = 100 % β-n = 7.4 14 % β-2n = ? | %β-n: weighted average of 6.8% 14 (1986ReZU) and 10.7% 33 (1993Ru01, earlier value was 4.2 9 in 1980Lu04). Others: 1986ReZU and 1986ReZS (1986Wa17 from the same group), 1984Ma39, 1982Ru01 and 1976Lu02 (same group as 1980Lu04 and 1993Ru01). E(level): %β-n: weighted average of 6.8% 14 (1986ReZU) and 10.7% 33 (1993Ru01, earlier value was 4.2 9 in 1980Lu04).

| 25 | (6-) | E(level): From plot (solid line in red) in Fig. 4a and text of 2016Ju02, based on the assignment of 357-227-103-86-50-(25) γ cascade to a ΔJ=1 sequence of levels from Jπ=(1-) to (7-) ground state forming members of πg9/2-1~#νf7/2 multiplet from shell model calculations for four different 2-qp configurations for relevant valence protons and neutrons, as described by 2016Ju02 in their Fig. 4a (black solid lines) and text. Evaluator indicates all the excited levels as tentative since the assignment of γ rays to 132In from the β-n decay of 133Cd and the ordering of the γ rays in the proposed cascade seems tenuous at the moment in the absence of observation of (133Cd)γ correlated events and γγ-coincidence relationships. Based on a statement by 2005Kr20, 2016Ju02 assume 100% β-n decay of 133Cd to 132In, however, evaluator’s perusal of 2005Kr20 paper indicates that authors of 2005Kr20 do not seem to claim 100% β-n decay branch of 133Cd based on solid experimental facts.

1973Ke06: 132In identified in separation of fission fragments
2002Di12: 132In from 238U(p,X) E=1 or 1.4 GeV; CERN/ISOLDE facility with the use of ISOLDE Resonance Ionization Laser Ion Source.
Mass deduced from Q(β-) measurement: 1995Me16
2015Lo04: 132In nuclide produced at RIBF-RIKEN facility in 9Be(238U,F) reaction at E=345 MeV/nucleon with an average intensity of 6×1010 ions/s. Identification of 132In was made by determining atomic Z and mass-to-charge ratio α/Q, where Q=charge state of the ions. The selectivity of ions was based on magnetic rigidity, time-of-flight and energy loss. The separated nuclei were implanted at a rate of 50 ions/s in a stack of eight double-sided silicon-strip detector (WAS3ABi), surrounded by EURICA array of 84 HPGe detectors. Correlations were recorded between the implanted ions and β rays. The half-life of 132In isotope was measured from the correlated ion-β decay curves and maximum likelihood analysis technique as described in 2014Xu07 (Phys. Rev. Lett. 113, 032505). Comparison of measured half-lives with FRDM+QRPA, KTUY+GT2 and DF3+CQRPA theoretical calculations
