Lifetime measurements of a triaxial band in 133 Ce

The Doppler shift attenuation method has been used to determined the transition quadrupole moment of a triaxial band belonging to the γ-soft nucleus, 133 Ce. Doppler broadened lineshape (DBLS) analysis has revealed the magnitude of the Q t value, to be ∼ 2.4 eb. This contribution provides new information of (i) the transition quadrupole moment of this band (ii) the life-times of in-band and sidefeeding transition and (iii) the relative deformations of coexisting nuclear shapes.
