Abstract The nuclide 129Ce was produced by a (16O, 4n) reaction on an enriched 117Sn target. Reaction products were transported to a shielded location by using a helium-jet tape transport system. An activity of 4.1 min in chemically separated cerium sample was identified as 129Ce. Based on x-γ-t and γ-γ-t coincidence measurements, the (EC+β+) decay scheme of 129Ce was proposed, and takes accounts of 50 observed γ-lines.
