“…It should be noted that the branching ratios given in Ref. [14] also produce an anomalously large rate of B͑E2͒ = 120 W.u. for this same transition.…”

“…We note that the recent neutron capture measurement [14] has better sensitivity to weak transitions. Spin and parity assignments, level energies, ␥-ray placements, branching ratios, multipole-mixing ratios, average attenuation factors, lifetimes, and transition rates for all observed levels are given in Table I.…”

“…Some features of the 126 Te level sequence may be reproduced using the pure U͑5͒ dynamical symmetry limit of the IBM-1 [14]; however, even with an O͑6͒ admixture, the IBM-1 model predicts too few levels below 3 MeV excitation [14,25,26].…”

“…The calculations were extended by Warr in Ref. [14] to 126 Te. The reader is referred to the original papers for details of parameter selection and model calculations; how-ever, the parameters are summarized in Table III.…”

“…The level scheme of 126 Te is known [2] from a series of measurements by a variety of probes, among which are reactor ͑n , nЈ␥͒ [3,4], EC and ␤ − decay [5][6][7][8], ͑␥ , ␥Ј͒ [9,10], ͑␣ ,2n͒ [11], ͑ 3 He, n͒ transfer [12], ͑p , pЈ͒ [13], and a recent ͑n , ␥͒ study [14].…”
