Low‐spin states in 122Cs

The decay of 122Ba to the odd‐odd 122Cs levels has been studied with on‐line mass‐separated samples at the Isocele facility. A complex level scheme including 42 new low‐spin excited states has been established using gamma and conversion electron spectroscopy techniques. From a series of new measurements, the T1/2=0.36s 122Cs isomeric state is proposed at 127 keV with 5− spin and parity assignments.
