Abstract：
A Total Routhian Surface(TRS) calculation are performed for studying triaxial superdeformation in the ¹⁶⁸Hf nuclei. The equilibrium deformation parameters are given. The shell and pairing correction energies are considered respectively, the formation mechanism of triaxial superdeformation is investigated. The large deformation is due to the neutron shell correction energy and high j intruder orbital πi_13/2.
