Description

The radioactive sources of sup(123,125,127,129)Ba from the spallation reaction have been studied with Ge(Li), Si(Li), NaI(Tl) and plastic detectors. On the basis of gamma-energies, intensities, energy sums and coincidence information, the decay scheme has been proposed for 127Ba. No high spin isomer of 127Ba has been observed. The lifetimes of 5/2+ → 1/2+ transitions in sup(123,125,127,129)Cs have been measured. No evidence for the shape isomerism in 127Cs has been found
