Quadrupole moment measurements of the 1/2{sup +}[660] (i{sub 13/2}) bands in {sup 133}Nd (N=73) and {sup 135}Nd (N=75) were performed using the Doppler-shift attenuation method. These results, coupled with the previously measured Q{sub 0} for the same configuration in {sup 137}Nd (N=77), clearly demonstrate a trend of decreasing quadrupole deformation with increasing neutron number. The larger quadrupole moment in {sup 133}Nd compared with that in {sup 135}Nd and {sup 137}Nd offers evidence for the role played by the large shell gap at N=72 for {beta}{sub 2}{approximately}0.35{endash}0.40 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 A{approximately}130 region. {copyright} {ital 1999} {ital The American Physical Society}
