The quadrupole moments for collective structures in the odd proton (Z = 59) 130Pr, 131Pr and 132Pr nuclei have been measured using the Doppler-shift attenuation method New information is presented on the shape-driving behaviour of the 9/2+[404] (g9/2) proton and 1/2-[541] (f7/2, h9/2) neutron Nilsson configurations. While the involvement of the former orbital leads to quadrupole deformations that are comparable to those observed for the socalled superdeformed bands in this mass region, the β2 values for structures that include the 1/2-[541] neutron are found to lie intermediate between those observed for normally deformed and superdeformed bands.
