Abstract：
The 1/2-[541] band in 171Lu is extended up to neutron crossing by using heavy-ion induced reaction ¹⁶⁰Gd(¹⁹F, 6n2p) at a bombarding energy of 92MeV.It shows delayed neutron crossing frequency in comparison with the even-even neighbors.Calculations based on cranked shell model suggest that the role played by the deformation-drving effect of the πh_9/2[541]1/2^－ orbit shouldn't be ignored in the delay of the bandcrossng in ¹⁷¹Lu.
