The intrinsic quadrupole moment Q{sub 0} of superdeformed rotational bands in A{approx}150 nuclei depends on the associated single-particle configuration. We have derived an empirical formula based on the additivity of effective quadrupole moments of single-particle orbitals that describes existing measurements from {sup 142}Sm to {sup 152}Dy . To further test the formula, the predicted Q{sub 0} moments for two superdeformed bands in {sup 146}Gd of 14.05 eb were confronted with a new measurement yielding 13.9{+-}0.4 eb and 13.9{+-}0.3 eb , respectively. This excellent agreement provides empirical evidence of extreme single-particle behavior in highly deformed, collective systems.
