“全同”超形变核转动带的量子群U_(qp)(u_2)模型的理论分析

Theoretical Analysis of an Uqp(u2) Model for the CongruentSuperdeformed rotational Bands

利用量子群Ｕｑｐ（ｕ２）模型计算了“１９１－１９２－１９３－１９４Ｈｇ超形变（ＳＤ）带的γ跃迁能Ｅγ，运动学转动惯量Ｊ（１）和动力学转动惯量Ｊ（２），顺排角动量之差（ｉ＝（Ｊ（１）（１９１－１９２－１９３－１９４Ｈｇ）－Ｊ（１）（１９２Ｈｇ））），并与实验值进行比较得到了满意的结果，此外，还利用Ｕｑｐ（ｕ２）模型的形变参量与核软度的关系式，计算出各ＳＤ带的核软度参数σ１与唯象分析给出的组态结构进行了比较分析。

Superdeformed rotational bands in 191-192-193-194Hg are analyzed by means of the Uqp(u2) model. An overall and excellent agreement between the calculated and observed spectra Eγ kinematic moment of inertia J(1) and dynamic moment of inertia J(2), the aligned angular momentum (i =(J(1)(191-193-194Hg) - J(1)(192Hg))) is obtained Further more, the nuclear softness in 191-192-193-194Hg are calculated by means of the Uqp (u2) model and drawn into the nuclear. configuration analysis.
