摘　　要：应用ＤａｖｙｄｏｖＦｉｌｉｐｐｏｖ的非轴对称转子模型，系统分析了锕系和稀土区偶偶核基带的转动能谱，提取了四极形变β和非轴对称度γ参数结果显示锕系和稀土区偶偶核基带四极形变是主要的。In the framework of the triaxial rotor model of Davydov and Filippov,the rotational spectra of the ground rotational bands for even even nuclei are analyzed.The deformation parameters β and γ which β represents the extent of quadrupole deformation and γ gives the degree of axial asymmetry are obtained by the fitting of rotational spectra in the ground rotational bands of actinide and rare earth even even nuclei.
