Abstract：
Using the N~ λ_nand E_r(I+2)/ E_r( I)~ Iplots, the latest experimental spectrum of the nucleus ¹⁵² ₆₆Dy ₈₆has been further analysed. It is point out that the ground band levels with I=8 ⁺belong to deformed collective band. But values of deformation are less than that of well deformed nuclei. And those levels are more vibrational like than rotational. The hint of pairing disapperance in nuclei ^167,169Yband ⁸⁴Zr is also discussed.
