摘要：

The EC/β+ and γ-decay of 35 min 111Sn to levels of 111In has been studied with Ge(Li) and NaI(Tl) detectors. A total of 16 γ-rays between 373 and 2325 keV are definitely assigned to the decay scheme. Excited states of 111In are established at 536 (111mIn), 1101, 1153, 1610, 1915, 2107, 2178, 2213 and 2325 keV. The isomer 7.3 min 111mIn is produced in 0.09% of the 111Sn decays. The spin-parity assignment of 111Sn is 7 2+ and those of 111In and 111mIn are 9 2+ and 1 2-, respectively. The EC transitions to all of the observed higher levels of 111In, except possibly the one at 1543 keV are allowed, leading to assignments of 5 2, 7 2, or 9 2+ for those levels. We obtained no evidence for any transitions to 1 2+ or 3 2+ levels similar to those in 115In and 117In that have been suggested as the lowest members of a rotational band. © 1968.
