Levels and transition probabilities in 120, 122, 124, 126, 128sn studied in the decay of In isotopes

“…The half-lives obtained for the 10 + , 7 − (in 124,126 Sn), and 5 − (in 124 Sn) isomeric states are fully in agreement with the literature values [1,3,11,13,37]. Therefore, the lifetimes in the even Sn isotopes are used only for the odd-even renormalization of the reduced transition probabilities (see Sec.…”

In124levels populated in theβdecay ofCd124

“…As noted above, the likely configuration of the 3 + ground state is πg 9/2 ⊗νd 3/2 [4]. The first excited state at 62.2 keV decays via an E1 [3] transition to the 3 + ground state and is therefore assigned a J π value of 2 − .…”

“…They are all assigned as 1 + based on the observed E1 multipolarities from Ref. [4] to the 62.2-keV 2 − state. These states likely arise from πg 9/2 ⊗νd 3/2 or πg 9/2 ⊗νs 1/2 configurations.…”

“…[3] is displayed in figure 1. Later work [4] assigned a value of 3 + to the ground state of 124 In based on a πg 9/2 ⊗νd 3/2 configuration. As the ground state of 124 Cd is 0 + , most of the β-decay strength would be expected to populate levels above the ground state.…”

Delayed neutron emission probabilities of gallium, bromine, rubidium, indium, antimony, iodine, and cesium precursors

“…~z7-13Zin The presence of isomers in most of the indium isotopes makes the data analysis and interpretation complicated, however. Detailed y-ray spectroscopy on neutron-rich indium isotopes has been performed at this laboratory by Fogelberg and Carl6 [23] for even-mass isotopes, by Fogelberg et al [19] and de Geer and Holm [24] for odd-mass isotopes. In the isotopes 124, 126, 12s, 13Oin there are two fldecaying isomers with similar half-lives, probably with spin and parity 3 + and 8-.…”
