Abstract
Five superdeformed (SD) bands have been observed in using the Gammasphere spectrometer. The measurement was performed with a backed target to obtain lifetime information from a Doppler-shift attenuation method analysis. It is proposed that the yrast SD band corresponds to the intruder configuration. The first excited band (band 2) is found to be identical to the yrast SD band. Band 3 is proposed to correspond to the proton-hole excitation coupled to the intruder configuration. Bands 4 and 5, the weakest SD bands seen in the present work, show similarities with band 3 and are most likely associated with a similar intruder configuration.
