Abstract

The intrinsic quadrupole moment Q₀ of superdeformed rotational bands in A∼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 ¹⁴²Sm to ¹⁵²Dy. To further test the formula, the predicted Q₀ moments for two superdeformed bands in ¹⁴⁶Gd of 14.05eb were confronted with a new measurement yielding 13.9±0.4eb and 13.9 ± 0.3eb, respectively. This excellent agreement provides empirical evidence of extreme single-particle behavior in highly deformed, collective systems.
