Description
The transition quadrupole moments Qt for the superdeformed band in 40Ca have been determined through thin-target Doppler-shift attenuation analyses. A best-fit value of Qt=1.30±0.05 e b is obtained when a single value is assumed for the entire band. Fitting separate quadrupole moments for in-band transitions decaying from the high-spin states and the presumably admixed low-spin states results in Qt(high)=1.81-0.26+0.41 e b and Qt(low)=1.18-0.05+0.06 e b, respectively. Qt values extracted for individual transitions in a Doppler-broadened line-shape analysis also indicate smaller Qt values at lower spins. These results are consistent with the interpretation of this band as an eight-particle-eight-hole superdeformed band with a significant admixture of less-collective configurations at low spins
