131TE c 1971Bl04: {+131}Sb(|b{+-}) T{-1/2}=23 min [from {+235}U(n,F)];
131TE2c measured |g's in 100-3700 keV energy range, |g|g-coin; Ge(Li)
131TE c 1975Hn01,1974GnZZ: {+131}Sb(|b{+-}) T{-1/2}=23 min [from {+235}U(n,F)];
131TE2c measured |g's in 20-4000 keV energy range, |g|g-coin. Ge(Li)
131TE c The decay scheme was based on {+131}Sb(|b{+-}) data of 1971Bl04 and
131TE2c 1975Hn01, and (d,p) data of 2003To08
131TE cB $1973Jo02 deduced |b-strength function from total-absorption |g-spectra
131TE cB E(A)$From 1977Lu06 (|b|g coin; Si, Ge(Li)). E|b(to 1876) is the
131TE2cB weighted average of 1.30 MeV {I10} and 1.32 MeV {I12}
131TE cB IB$From net |g feeding of each level
131TE cG E$Weighted average from 1975Hn01 and 1971Bl04 when available,
131TE2cG except as noted. 1971Bl04 did not measure transitions below 276 keV
131TE cG TI$From total feeding to 182 level of 6.5% {I9} and %IT=25.9 {I5}
131TE cG RI$From 1975Hn01, except as noted
131TE cG E(A),M(B) From the adopted gammas

131TE cG E(E),RI(F)$Exhibits complex T{-1/2} (1975Hn01)
131TE cG E(I) Not reported by 1971Bl04
131TE cG E,RI(M)$From 1971Bl04. Not reported by 1975Hn01
131TE cG E(O)$Placed as deexciting 2399 by 1975Hn01 and deexciting 2662 by
131TE2cG 1971Bl04
131TE cG E(Q) Placed as deexciting 2226 and 2335 by 1975Hn01
131TE cL $The levels at 1036, 1467 and 1853 suggested in 1971Bl04 are not
131TE2cL adopted as they are missing in reaction data and are not obtained in
131TE3cL coincidences. 1975Hn01 suggested level at 2759 based on comparison to
131TE3cL available reaction data; however, L(d,p)=1 for 2752 seems inconsistent
131TE4cL with the deduced feedings of this level, and the level is not included
131TE5cL too. The level at 2017 is adopted as it suggested in 1975Hn01 and
131TE6cL 2003To08
131TE cL E$From least-squares fit to E|g's
131TE cL J$From (d,p) data 2003To08. See 1971Bl04 and 1975Hn01 for other
