Nuclear structure calculations: 2004Yo04 (levels, transition rates), 2000Dm04 (anapole moments), 1999Dr18 (IBA model), 1990Lo16 (levels, IBFM model), 1987Mi15 (levels, transition rates, magnetic moment, Q), 1985Ha34 (levels), 1984Ab01 (yrast levels)

For 86 neutron resonances from 102 eV to 10.6 keV, see 134Ba(n,γ):resonances dataset compiled from 1996Ko27. See also 2006MuZX evaluation.

E(level): From least-squares fit to Eγ’s including primary γ rays from (n,γ) reactions, 0.3 keV uncertainty when not stated. For 86 neutron resonances in the range 102 eV to 10.6 keV see 134Ba(n,γ):resonances dataset.

Jπ(level): For high-spin (J>11/2), the assignments are as proposed by 2006Ch51 based on their γγ(θ)(DCO) data and systematics in this mass region. The evaluators place all the assignments in parentheses

M(γ): For γ rays from low-spin levels, the assignments are from ce data in 135La ε decay. The mult=Q and d are from DCO ratios in 130Te(9Be,4nγ), mult=Q corresponds to ΔJ=2, quadrupole and mult=d to ΔJ=1, dipole (with possible quadrupole admixture for Δπ=no). The mult=Q most likely corresponds to E2 transition
