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.
