(EC +β+) decay of130Ce
1996
The nuclide130Ce was produced by a (16O, 4n) reaction on an enriched118Sn target. Reaction products were transported to a shielded location by using a heliumjet tape transport system. A 22.9 min activity in chemically separated cerium sample was identified as130Ce. The (EC+β +) decay scheme of130Ce was proposed for the first time. This scheme includes 108γ-lines, 107γ-lines among them being new. More than 13 1+ low-lying states of130La are populated in the decay of130Ce. Two new isomers with half-life of 77±10 ns and 17±5 ns were observed by means of delayedγ-γ coincidence measurements.
