【摘要】 提出了两种新形式的约束哈特里－福克方法，并在ＳＵ（２）×ＳＵ（２）双准自旋模型中讨论了它们的解．研究了建立严格好准自旋态的对角化方法，并对好准自旋态能错的特点和近似带结构的划分进行了探讨．两种ＣＨＰ能谱与严格能谱的比较表明，它们都具有转动谱的特征；在相互作用不太强的体系中，新方案是获得好准自旋态的、能产生多带能谱结构的有效方法．更多还原

【Abstract】 Two new forms of the constrained Hartree-Fock(CHF) methods are proposed,and their solutions are discussed in SU(2)×SU(2) Double-quasi-spin model. The diagonalization methods for establishing the exact solutions |JK>and |J> are discussed. It is found that the two kinds of CHF spectra possess the characters of the rotational spectra, and that the new prescriptions are the effective methods to obtain the spectra with multi-band structue.更多还原
