The quadrupole moments of three decoupled bands in the odd-odd nuclei {sup 130}Pr and {sup 132}Pr were measured using the Doppler shift attenuation method in the bombardment of {sup 105}Pd with {sup 35}Cl at 173 MeV. The {pi}h{sub 11/2}{circle_times}{nu}(f{sub 7/2},h{sub 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{sup {minus}}[541] (f{sub 7/2},h{sub 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. {copyright} {ital 1999} {ital The American Physical Society}
