The quadrupole moments of highly deformed bands in {sup 134,135}Nd and {sup 131}Ce have been determined using the Doppler-shift attenuation method. The obtained Q{sub 0} values show no clear dependence on the number of occupied {nu}i{sub 13/2} intruder orbitals. Cranked shell model calculations indicate that the charge-quadrupole moments of the highly deformed bands decrease with increasing spin. The expected increase in deformation induced by the {nu}i{sub 13/2} orbital in two bands of {sup 134}Nd is attenuated by a rotation-induced shrinking effect driving the nucleus towards smaller deformation. {copyright} {ital 1998} {ital The American Physical Society}
