The two-dimensional total routhian surface calculations have been carried out to study the triaxial su- perdeformed structure of a neutron-rich nucleus ~(173)Hf firstly.In particular the effects of the rotational frequency ω and pairing-energy gap parameter A are discussed in detail in the course of shaping its triaxial superdeformation;additionally the neutron-shell correction energy is analyzed with emphasis in the confirmed triaxial superdeformed nucleus 请下载后查看，本文暂不支持在线获取查看简介。(173)Hf. Finally,more systematical results have been investigated for some confirmed superdeformed nuclei experimentally and a few predicted triaxial superdeformed nuclei theoretically with quadropole deformation ε_2≈0.4 and triaxial deformation γ≈20°or 30°in the Z=72 region.
