摘要
The nuclide ^(129)Ce was produced by a(^(16)O,4n)reaction on an enriched ^(117)Sn 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 ^(129)Ce.Based on x-γ-t andγ-γ-t coincidence measurements,the(EC+β+)decay scheme of ^(129)Ce was proposed,and takes accounts of 50 observedγ-lines.
