| 摘 要： | 从Ｄａｖｙｄｏｖ－Ｆｉｌｉｐｐｏｖ的非轴对称转子模型出发，考虑三轴γ形变较小，用微扰方法，给出了原子核转动谱的新公式，拟合了锕系和稀土区偶偶核基带转动谱以及１９０区偶Ａ核超形变（ＳＤ）带的Ｅ２跃迁谱。结果显示，根据Ｄａｖｙｄｏｖ－Ｆｉｌｉｐｐｏｖ模型导出的转动谱公式，不仅较好地再现了锕系和稀土区偶偶核基带的转动谱以及１９０区偶Ａ核ＳＤ带的Ｅ２跃迁谱，而且能够给出具有明显物理意义的四极形变β和非轴对称度γ参数。

| Abstract: | A new expression for the rotational spectra of even A nuclei is derived from the rotational spectra up to very high spins. An overall and excellent agreement between the calculated and observed spextra is obtained for the actinide, the rare-earth deformed nuclei and the superdeformed nuclei in A～ 190 region, a small axial asymmetry effects have been taken into account. |

| Keywords: | axial asymmetry superdeformed band γ deformation |
