摘　　要：采用相互作用玻色子模型研究了140-162Gd偶偶核的低能谱和电磁跃迁,应用一个U(5)→SU(3)的简化哈密顿量很好地描述它们的低能谱和电磁跃迁过渡．结果表明140-162Gd同位素核基本上属于U(5)→SU(3)的过渡核．Spectra and electromagnetic transition for the even-even ^140-262Gd isotopes are studied in the framework of the interacting boson model. A schematic Hamiltonian can be used to describe their spectra and transition. The results show that ^140-262Gd are in the transition from the vibrational limit to rotational limit.
