论文摘要
在集体的Bohr Hamiltonian中,采用质量张量作为集体坐标的函数,已经证明了其对描述核结构的重要性。另一方面,对于奇数核,旋转和单粒子运动之间的科里奥利相互作用显着影响核激发态的结构。在最近开发的扩展的Bohr Hamiltonian的框架内,通过考虑旋转的不同质量参数以及两个\ betha和γ振动的不同质量参数,并考虑了科里奥利的贡献,我们研究了173yb,163yb,163y,155euu和1533eu unuclei coriolis的贡献。计算激发态能量和B(E2)过渡概率,并将其与可用的实验数据进行比较。此外,我们研究了DDMF和Coriolis力对核观测值的影响。
Within the collective Bohr Hamiltonian, the adoption of a mass tensor as a function of collective coordinates has demonstrated its importance for describing the structure of nuclei. On the other hand, for odd-mass nuclei, the Coriolis interaction between the rotational and single-particle motions affects significantly the structure of nuclear excited states. In the framework of a recently developed extended Bohr Hamiltonian, by considering the Deformation-Dependent Mass Formalism whith different mass parameters for the rotation and the two \betha and γvibrations and taking into account the Coriolis contribution, we investigate the bands structure of the 173Yb, 163Dy, 155Eu and 153Eu nuclei. Excited-state energies and B(E2) transition probabilities are calculated and compared with the available experimental data. Besides, we investigate the effect of DDMF and the Coriolis force on nuclear observables.
