轴对称超形变和三轴超形变核态性质的研究

利用轴对称超形变和三轴超形变模型研究了¹⁶⁵Lu π[660 1/2]带.两种模型计算的γ跃迁能量都和实验值较好地符合.然而,能量的signature颤动指数,三轴因子,两类动力学电四极矩之比存在明显的差别,这些差别可以用来识别三轴超形变核态.

Study of Nuclear Behavior in Axially-Symmetric Superdeformation and Triaxial Superdeformation

Using axially-symmetric and triaxial superdeformed models [660 1/2] bandin 165Lu is investigated. The observed transition energies can be reproduced quite well in both models. However, the signature staggering index, triaxiality factor andthe ratio of dynamical quadrupole moment to in axially-symmetricsuperdeformed model are obviously different from those in triaxial superdeformedmodel, which may be used to identify the deviation of nuclear shape from axialsymmetry. Thus, the energy spectra are not decisive to draw the nuclear shape.Emphasis must be Placed on the properties of electromagnetic transitions.
