摘要: 采用IBM模型研究了^142-164Dy核的低能正宇称态的能谱和电磁跃迁。应用U(5)→SU(3)的简化哈密顿量较好地描述了它们的能谱和电磁跃迁。研究结果表明，该核基本属于U(5)→SU(3)的过渡核Spectra and E2 transition rates for the eveneven 142-164Dy isotopes are studied in the framework of the interacting boson model. A schematic Hamiltonian capable of describing their spectra and transition is used. It is found that the eveneven 142-164Dy isotopes are in the transition from U(5)to SU(3) dynamical symmetry.Abstract: Spectra and E2 transition rates for the eveneven 142-164Dy isotopes are studied in the framework of the interacting boson model.
