Abstract
The quadrupole moments of highly deformed bands in Nd-134,Nd-135 and Ce-131 have been determined using the Doppler-shift attenuation method. The obtai ned Q(0) values show no clear dependence on the number of occupied nu i13/2 intruder orbitals. Cranked shell model calculations indicate that the char ge-quadrupole moments of the highly deformed bands decrease with increasing spin. The expected increase in deformation induced by the nu i(13/2) orbit al in the two bands of Nd-134 is attenuated by a rotation-induced shrinking effect driving the nucleus towards smaller deformation.
