具有三度转动对称轴的八极形变

OCTUPOLE DEFORMATION OF THREE FOLD ROTATIONAL AXIS

介绍了各种非轴对称八极形变的对称性质，着重讨论了其中的α３３形变，并利用基于ＷｏｏｄｓＳａｘｏｎ势的Ｓｔｒｕｔｉｎｓｋｙ壳修正方法，计算了Ｐｏ，Ｒｎ，Ｒａ和Ｔｈ等原子核的总位能面。

Symmetry properties of non axial octupole shapes,particularly for α 33 deformed shapes,are discussed.With the Strutinsky method based on Woods Saxon potential,the total routhian surfaces for nuclei Po,Rn,Ra and Th are constructed and the evidence of the existence of the exotic octupole shapes with a three fold rotational symmetry is presented.
