Abstract Three-dimensional total Routhian surface calculations are carried out to determine the triaxial superdeformation of odd--odd nucleus 168Lu. One of the new four rotational bands observed in the experiment is identified as a triaxial superdeformed band, in which the neutron shell correction energy plays a key role and the deformation-driving effect of high j intruder orbital plays an additional role in the formation of triaxial superdeformation shape. Its deformation parameters (ε2,ε4, γ) are derived from the analysis, which can reproduce the experimental assignment.
