The two-dimensional total routhian surface calculations have been carried out to study the triaxial superdeformed structure of a neutron-rich nucleus
173Hf firstly. In particular the effects of the rotational frequency ω and pairing-energy gap parameter Δ
are discussed in detail in the course of shaping its triaxial superdeformation; additionally the neutron-shell correction energy is
analyzed with emphasis in the confirmed triaxial superdeformed nucleus 173Hf. Finally, more systematical results have been investigated for some confirmed superdeformed nuclei experimentally and a few predicted triaxial superdeformed nuclei theoretically with quadropole deformation ε2≈0.4 and triaxial deformation
γ≈20º or
30º in the Z=72 region. 相似文献

首先概述了对A≈150区超形变带的自旋指定的进展情况, 到目前为止, 所提出的各种方法对该区超形变带自旋值的指定并不一致. 发现了该区超形变带的实验能谱特性和动力学转动惯量的特性. 并将此特性用于指定A≈150区超形变带的自旋. 相似文献

The variation in moments of inertia (J(1) and J(2)) with rotational frequency for the superdeformed bandsin odd-odd nuclei, 194Tl(la,lb), is investigated by using the particle-number conserving method for treating the pairinginteraction (monopole and quadrupole). The observed variations of J(1) and J(2) with ω are reproduced quite well inthe calculation and the contributions from each major shell are clearly displayed. 相似文献

用双参数量子群Uqp(u2)理论模型公式对A~190区47条超形变(SD)转动带进行了系统分析.计算得到的Eγ跃迁谱与实验较好地吻合;按转动带自旋指定的3种方案确定194Hg(1),194Pb(1)的带首自旋,结果与实验一致.此外,进一步讨论了核软度参数σ1的物理意义,发现一对旋称对偶带的σ1几乎全等. 相似文献

With the supersymmetry scheme including many-body interactions, the global property and the △I = 4bifurcation in the superdeformed (SD) bands of odd-odd nuclei in A ~ 150 mass region are investigated systematically.Good results for the γ-ray energies, the dynamical moments of inertia, and energy differences △ Eγ - △ Erefγ are obtained.It shows that this approach is quite powerful in describing not only the SD bands in even-even and odd-A nuclei butalso those in odd-odd nuclei in the mass region. 相似文献
