| 摘 要： | 利用 Ｄａｖｙｄｏｖ － Ｆｉｌｉｐｐｏｖ 模型导出的转动谱公式，分析了１９０ 区偶－ 偶 Ｈｇ ， Ｐｂ 和 Ｐｏ 同位素的 Ｅ２ 跃迁谱，得到了四极形变β和非轴对称度γ参数，结果表明：偶－ 偶 Ｈｇ ， Ｐｂ 和 Ｐｏ 同位素的四极形变是主要的，非轴对称度γ形变也对能谱产生了重要的影响。

Description of Nuclear Superdeformed States in the Davydov-Filippov Model |
| |
| Abstract: | We show in this paper that the superdeformed (SD) nuclear states can be described with a two parameter formula which is derived from the Davydov-Filippov model. The E 2transition γ-ray energies of yrast SD bands in even even Hg,Pb and Po isotopes can be reproduced with satisfactory results. The deformation parametersβand γ,which β represents the extent of quandrupole deformation can also be obtained by fitting of rotational spectra of SD bands. |
