Abstract
The electric quadrupole moment of the 9/2(-) isomer in the Ta-171 nucl eus, populated in the Tb-159(O-16, 4n gamma)Ta-171 reaction, has been measured for the first time using the TDPAD technique. The measured va lue Q(9/2(-)) = 3.09(19) b and B(M1)/B(E2) ratios, deduced from the ex isting gamma-ray spectroscopic data, have been used to derive shape pa rameters for the pi h(11/2) band based on this isomer. The present res ults are consistent with a quadrupole deformation beta = 0.22(1), gamm a = 0 degrees +/- 10 degrees.
