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-γcoincidence measurements.

209Fr has been produced by irradiation of197Au with16O,and studied using a He-jet recoil tape transport system.A decay scheme is proposed for the first time,based on X-γ and γ-γ coincidence measurements,which takes account of 20 observed γ-rays. The branching ratio for (EC+β+) decay of209Fr has been estimated to be 3.0±1.5%. Five members of low-lying states in209Rn can be explained with the configuration [(210Rn 2+)(νf5/2)−1].

Unknownβ-delayed proton precursor135Gd has been synthesized by the reaction106Cd (32S, 3n) and identified using a helium-jet recoil fast tape-transport system with aγ(X)-p coincidence measurements. Itsβ-delayed proton spectrum has been observed. The half-life of135Gd decay has been determined to be 1.1±0.2 s.
