Abstract
The quadrupole moment for the pg_9/2 $\otimes$ nh_11/2 band in the 130^Pr nucleus has been measured using the Doppler-shift attenuation method. A centroid shift analysis was carried out and a value of Q₀=6.1 $\pm$ 0.4 eb, corresponding to an axial prolate deformation of $\beta_{2}$ =0.35(3), has been determined. This is the first direct experimental confirmation of the deformation-driving character of the pg_9/2 orbital in an odd-odd nucleus in the A $\sim$ 135 superdeformed region.
