摘要：
Superdeformed bands observed in Ce-131, Ce-132, and Ce-133 have sequences of gamma-ray transition energies that exhibit a Delta I = 2 staggering. This staggering has different characteristics to that seen in previously known cases in other mass regions. The energy staggering starts at low rotational frequency (HBAR omega = 3 MeV for Ce-131) at a magnitude of similar to+/-0.3 keV, dies away to zero at intermediate frequency (Aw = 0.6 - 0.7 MeV), and reappears at higher frequencies (HBAR omega similar to 0.7 MeV).
