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 even-even ^(142-164)Dy 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 even-even ^(142-164)Dy isotopes are in the transition from U(5) to SU(3) dynamical symmetry.
