Transition Quadrupole Moments at High Spin in 133Nd Rotational Bands

Lifetime measurements on the high-spin rotational bands in Nd-133 have been carried out by the Doppler-shift attenuation method using the GASP array. The Nd-133 nuclei were populated in the Pd-104(S-32, 2pn) reaction at a bombarding energy of 135 MeV. The Doppler-broadened line shapes were analyzed for Au-backed and Gd-backed targets. Values of Q(t) = 4.7(5), 5.6(5), and 7.4(4) eb have been determined for the mean transitional quadrupole moments of the ground-state band, the negative-parity band involving the neutron h(9/2)/f(7/2) intruder orbitals, and the band built on the neutron [660]1/2(+) intruder orbital, respectively. The presently determined quadrupole moments are compared with those of the low-spin members of the bands derived elsewhere from recoil distance method measurements. The observed polarizing effects of the neutron intruder orbitals are compared with cranked shell model predictions.
