Abstract

The quadrupole moments of three decoupled bands in the odd-odd nuclei $^{130} \Pr$ and $^{132} \Pr$ were measured using the Doppler shift attenuation method in the bombardment of $^{105}$ Pd with $^{35}$ Cl at 173 MeV. The $π h_{11 / 2} \otimes ν$ ${(f}_{7 / 2},$ $h_{9 / 2})$ configuration was assigned to these structures on the basis of the observed in-band properties and relative deformations. New information is presented on the shape-driving behavior of the ${1 / 2}^{-}$ [541] ${(f}_{7 / 2},$ $h_{9 / 2})$ intruder neutron orbital, whose involvement in a particular configuration leads to quadrupole deformation values which are intermediate between those known for normally deformed and so-called superdeformed bands in this mass region.
