Quadrupole moment measurements of the [Formula Presented] bands in [Formula Presented] and [Formula Presented] were performed using the Doppler-shift attenuation method. These results, coupled with the previously measured [Formula Presented] for the same configuration in [Formula Presented], clearly demonstrate a trend of decreasing quadrupole deformation with increasing neutron number. The larger quadrupole moment in [Formula Presented] compared with that in [Formula Presented] and [Formula Presented] offers evidence for the role played by the large shell gap at [Formula Presented] for [Formula Presented] in stabilizing the shape at enhanced deformation. The comparison of results from gating below and above the level of interest provides information on the time scale of the sidefeeding contributions to highly deformed structures in the [Formula Presented] region.
