摘要
在通常感兴趣的角频率范围内(ω≤0.5MeV)分别计算了单,j-CSM哈密顿量H_(CSM)的相当精确的低激发态和能谱,及其在HFB近似下的哈密顿量H'_(GSM)的低激发态和能谱,尽管有一部分结果相似(晕带与次晕带发生第一次交叉,交叉频率值),但两者存在重大差别,特别是晕带与次晕带在带交叉附近的性质及带相互作用强度.因此,CHFB方法的理论基础需要重新探讨,这里可能涉及Coriolis减弱问题.
The accurate solutions for the low-lying eiginvalues and eigenstates of the single-j CSM hamiltonian have been obtained and are compared with the HFB approximation. There exist a world of difference between the two, especially the behaviour of the yrast and the yrare bands near the bandcrossing and the band interaction strength. The theoretical foundation of the CHFB. method for treating the rotating nuclei needs reexamination.
