General Comments:

Assignment: Observation of the band structures of 122Ce and 122La, the daughter, and comparison with the band structures of 124-128Ce.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQβ=640 keV, ΔS(n)=640 keV, ΔS(p)=640 keV,ΔQ(α)=450 keV from atomic mass systematics (2003Au03)
