Abstract

Two excited superdeformed (SD) bands have been observed in $^{132} Ce$ using the Eurogam gamma-ray spectrometer. Possible configurations are proposed in terms of particle-hole excitation from a theoretical analysis based on the cranking approximation with the Woods-Saxon deformed potential. From relationships between $γ$ -ray energies of SD bands in $^{132} Ce$ and $^{131} Ce$ , the existence of identical bands and approximately quantized alignments is established in the mass 130 region.
