【摘要】 原子核的低能集体谱依赖于它的核子数。本文在没有用动力学对称性假定的IBA框架中讨论了这一问题。结果表明,从振动能谱向转动能谱的过渡主要是由价核子数增加引起的。更多还原

【Abstract】 Low-lying collective spectrum of a nucleus depends on its nucleon number. In this paper, the argument is discussed in the framework of IBA without using dynamical symmetry assumption. The result shows that the transition from vibrational to rotational spectrum is mainly caused by the increase of valence nucleon number.更多还原
