Description

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. (author)
