英文摘要High-spin states in Ta-171 were populated through the heavy-ion fusion-evaporation reaction Gd-157 (F-19, 5n)(171) Ta at 105MeV beam energy. Lifetimes of the levels of the pi h(9/2)1/2[541] band have been measured by using the Doppler shift attenuation method. The transition quadrupole moments (Q(t)) and the quadrupole deformation (beta(2)) have been extracted. Both beta(2) and Q(t) values decrease slightly with increasing rotational frequency. The average beta(2) value of 0.26 is 18% larger than that of the pi h(11/2) 9/2[514] band. Total Routhian Surface calculations have been performed with the non-axial deformed Woods-Saxon potential and the predicted values of the quadrupole deformation beta(2) are in good agreement with that deduced from our lifetime measurement. The shape-driving effect is discussed.
