E(level): From least-squares fit to Eγ data

Jπ(level): For low spins (J<8), the assignments are essentially suggested by 1989St06 on the basis of 1+ for 1325 and 2268 levels (from log ft values); (4)+ for 132Sb g.s.; multipolarity of transitions; and γγ(θ) data from 1995Ma02. Other Jπ choices are possible if Jπ(132Sb g.s.)=3+. Comparison with shell-model calculations is also used in assigning Jπ values

T1/2(level): From βγ(t) (1995Ma02) in 132Sn β- decay, unless otherwise indicated

Reverse ordering of 957-2464 is possible from intensity considerations (2001Bh06) with an intermediate level at 1982+x instead of that at 3489+x, however, based on model considerations and decay characteristics discussed by 2001Bh06, the latter is preferred.
