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

利用粒子 -转子模型研究三轴超形变核态,讨论了区别轴对称超形变和三轴超形变可能的实验信息.为了直接从实验上识别三轴超形变带,必须同时测量能谱和电磁跃迁几率. Current developments in triaxial superdeformed states in nuclei are discussed from a theoretical perspective. A detailed analysis of superdeformed triaxial bands is made with particle-rotor model. Experimental information which may differentiate triaxial superdeformation from axially-symmetric superdeformation is disussed. In order to identify the superdeformed triaxial bands both the energy spectra and electromagnetic transition. 相似文献

By using Total Routhian Surface (TRS) method the deformation of the nucleus ^160Yb
is studied. The result shows that the triaxial superdeformed state exists with deformation parameters ε2 = 0.38 and γ = 21°, where proton shell correction energy plays a key role, and the sum of two quasi-proton particle energies gives an additional driving effect. The rotational energy also has an additional role in the formation of triaxial superdeformed. 相似文献

Two-dimensional total routhian surface (TRS) calculations are carried out to determine the triaxial superdeformation (TSD) of the even-even nucleus 174W, and the result indicates that TSD state exists with deformation parameters ε2=0.42 and γ=34.7°. In the same way, the total routhian surfaces for the nuclei 172,176W are also calculated. It shows that the neutron shell correction energy plays a key role in the formation of TSD nuclei 172,174,176W, while the high j intruder orbitals and rotational energy are also crucial in the formation mechanism. 相似文献
