Levels and transitions in126Te

Abstract

Abstract. The decay of 126Sb to 126Te is studied by use of Ge(Li) detectors in singles and coincidence arrangements. The gamma-gamma directional correlations of six cascades are measured. A level scheme is constructed where all transitions observed are located. The characteristics of several of the levels are assigned, on basis of the log ft values deduced and the directional correlation results. Mixing ratios are deduced for three transitions. From the comparison of the relative intensities of E1 and E2 transitions depopulating the same levels, three E 1 transitions are concluded to be strongly retarded.

Finding the Remnants of the Milky Way's Last Neutron Star Mergers

“…Among these isotopes, 126 Sn, which resides close to the second r-process peak, with t 1/2 = 2.3 × 10 5 yr, is the most promising candidate for NSM remnant γ-ray searches. First, the decay sequence of 126 Sn → 126 Sb → 126 Te produces a few strong lines with energy (intensity) of 414.7 keV (98%), 666.3 keV (100%), 695.0 keV (97%) (Orth et al 1971;Bargholtz et al 1975;Smith et al 1976) 2 Second, the production of nuclei near the second peak, like 126 Sn, is almost guaranteed in every NSM. Motivated thus, we evaluate the detection prospect of 126 Sn decay γ-rays in Sec.…”

“…Therefore, the decay line intensities from 126 Sb are a linear-superposition of these two sub-channels. For example, a 720.7 keV line has a 53.80(24)% intensity(Bargholtz et al 1975) via the latter channel but will not be produced via the former, which results in a total intensity of only ≈ 7%.3 The Solar r abundances inSneden et al (2008) are given for elements with charge number Z ≥ 69. However, we do not include those between 69 ≤ A ≤ 89 because their solar r abundances may have received large contribution from other sites like core collapse SNe.…”

“…[21]. The previous beta decay study did not observe this transition because it was masked by contamination from a 928.3 keV gamma-ray from the decay of 126 Sb [24]. Ag is dominated by a large amount of feeding to negative parity states.…”
