用三维TRS(totalrouthiansurface)自洽理论对奇奇核164Lu的位能面进行了计算,计算结果与实验上得到的ε2=0.38基本一致,从而从理论上确认了164Lu是三轴超形变核,并且指出了存在三轴超形变带的两个组态. Total routhian surface in~(164)Lu nuclei is calculated according to the three dimensional Total Routhian Surface (TRS) theory. The result of the calculation is in agreement with the experiment. At the same time, two TSD bands could be assigned to the configuration(π\(1/2), α=1/2)(ν\(5/2), α=1/2), (π\(1/2), α=1/2)(ν\(3/2), α=-1/2). 相似文献

采用TRS方法对曾经在低转动频率下计算过的175Hf进行较高转动频率的计算, 结果 在原来没有第二极小值的总位能面中出现了极小值, 进而分析它的产生机制, 并对两个 频率下的各部分能量进行了比较. 相似文献

高旋旋超形变研究是高自旋态物理研究中的热门课题之一。作者是在中国原子能科学研究院的HI-13串列加速器上通过^152Sm(^19F,4n)^167Lu反应观测到^167Lu的一个新的转动带。 相似文献

通过152Sm(19F,4n)167Lu反应观测到167Lu的一个新的转动带.发现其高自旋γ跃迁能量与163Lu和165Lu三轴超形变的十分相近.按基于推转壳模型的总转动位能面计算,167Lu和前人工作中的171Ta[660]1/2转动带被指定为三轴超形变带.讨论了该核区三轴超形变的形成机制. 相似文献

简述了超形变原子核全同带的研究进展情况,并以Bohr-Mottelson的I(I+1)展开转动谱公式对部分典型的超形变带进行了分析.发现所谓全同带的确只是两个带的J(2)比较接近,它们的J(1)和J0并不相等,而且signature对偶带更接近全同. 相似文献

Properties of the triaxial superdeformed (TSD) bands of odd-A Lu isotopes are investigated systematically within the supersymmetry scheme including many-body interactions and a perturbation possessing the S0(5) (or SU(5)) symmetry on the rotational symmetry. Quantitatively good results of the γ-ray energies, the dynamical moments of inertia and the spin of the TSD bands in odd-A Lu isotopes are obtained. The calculation shows that the competition between the pairing and anti-pairing effects exists in these TSD bands. Meanwhile, the SU(3) symmetry in TSD bands are broken more seriously than in superdeformed (SD) bands. 相似文献

The triaxially superdeformed states in 162Lu are investigated using the three-dimensional total routhian surface calculation, and the deformation parameters and the likely configuration are given. The shell and pairing correction energies are considered respectively, and the formation mechanism of triaxial superdeformation is investigated. 相似文献
