Description

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 so-called 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.
