Abstract By a systematic on-line cesium mass separation fromA=122 toA=132 and subsequent gamma and electron decay spectroscopy at very low energy, new isomers have been precisely identified:122m Cs (T 1/2=0.36±0.02 s),124m Cs (T 1/2=6.3±0.2 s) and130m Cs (T 1/2=3.46±0.06 min). Detailed level schemes are given for both124m Cs and130m Cs. Comparison of excited levels known in the odd-odd nuclei of the same region shows that more experimental informations are needed to propose a clear and realistic picture of the nuclear states structure.
