本文用全Routhian曲面（TRS）方法研究了~（160）Yb核的形变。结果表明，存在三轴超形变态，形变参数为γ 2 = 0.38，γ = 21°，其中质子壳层修正能起关键作用，两个准质子粒子能量之和起附加驱动作用.转动能在三轴超形变的形成中也有附加作用。
By using Total Routhian Surface (TRS) method the deformation of the nucleus 160Yb is studied. The result shows that the triaxial superdeformed state exists with deformation parameters ∊2 = 0.38 and γ = 21°, where proton shell correction energy plays a key role, and the sum of two quasi-proton particle energies gives an additional driving effect. The rotational energy also has an additional role in the formation of triaxial superdeformed.
