Abstract

The transition quadrupole moments Q_t for the superdeformed band in ⁴⁰Ca have been determined through thin-target Doppler-shift attenuation analyses. A best-fit value of Q_t = 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 Q_t(high) = 1.81_-0.26^+0.41 e b and Q_t(low) = 1.18_-0.05^+0.06 respectively, Q_t values extracted for individual transitions in a Doppler-broadened line-shape analysis also indicate smaller Q_t 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.
