将两准粒子加轴对称转子模型扩展到三轴形变, 对奇奇核102Rh的旋称反转进行了研究和分析, 结果表明, 可能的旋称反转机制 (即低K 空间n p相互作用和科氏力的相互竞争), 对于A=100质量区奇奇核也是适用的, 三轴形变可以明显地改进能谱的振荡特性. The model of an axially symmetric rotor plus two quasi particles for the Signature Inversion (SI) in odd odd nuclei is generalized to the triaxial deformation. The calculation of the odd odd nucleus 102Rh shows that the possible SI mechanism (i. e., the competition between the n p interaction and the coriolis force in low K space) is also appropriate for odd odd nuclei in the A=100 region. A triaxial shape can improve the vibration property of the rotational spectra remarkably. 相似文献

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

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

A two-dimensional Total Routhian Surface(TRS) calculation is carried out in order to ascertain if there is triaxial superdeformation in 175Hf. A five quasi-particle configuration is chosen in the calculation. Unfortunately, the TRS minimum does not show up in the total potential energy surface. 相似文献

利用在束核谱学实验技术,建立了169Re基于9/2-[514]组态的强耦合转动带.该带在已知的奇ARe核中具有最大的低自旋旋称劈列.对于奇ARe中的9/2-[514]转动带,研究了它们的能量旋称劈列和M1跃迁矩阵元相对旋称劈列与核形状偏离轴对称的关系,揭示了非常缺中子的奇ARe核具有相当的负三轴形变. High-spin states in~(169)Re were studied and resulted in the identification of a strongly coupled band based on the 9/2~(-)\ Nilsson state. The 9/2~(-)\ band in~(169)Re shows the largest signature splitting at low spin among the known odd mass Re isotopes. For the 9/2~(-)\ bands in light odd-A Re isotopes, the signature splitting of the Routhians and its relation with the signature dependence of M1 transition matrix elements are investigated in connection with the deviation of nuclear shape from axial symme... 相似文献

Udlizing the consistent Q framework via an additional three-body potendal of L=3 in the interacting boson model,ananalytical descdption for the triaxial deformation in the O(6)-like nuclei is given on the basis of the intrinsic frame.The deformation parameters β and γof the even-even Xe,Ba and Ce isotopes are calculated.The calculated results are in good agree nont with the results of the rigid triaxial rotor model. 相似文献
