Abstract：
Recently a new positive parity rotational band was observed,its moment of inertia is a bit larger than of ground,β and γ bands for some even-even nuclei of the actinide and rare-earth regions,and also was negative parity band.These facts can be interpreted by vibron model and octuple deformation.By a simple geometrical figure the more stretch of the polarized core was quantitatively estimated when there was α-cluster in the surface region of the core.If there is this polarized effect,it ought to be behaved in the angular distribution of α-decay.
