Pr nuclei near mass 
Abstract
The quadrupole moments for collective structures in the odd proton (Z = 59) 
, 
and 
nuclei have been measured using the Doppler-shift attenuation method. New information is presented on the shape-driving behaviour of the 
[404] 
proton and 
[541] (
, 
) 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 
values for structures that include the 1/
[541] neutron are found to lie intermediate between those observed for normally deformed and superdeformed bands.
