• A new method is proposed in order to avoid the strange behaviour of the solution of the HFBC model in the band crossing region. For this purpose, the intrinsic states in a rotating nucleus are defined by excluding the interaction between basic rotational bands from the original cranked Hamiltonian, which are defined in the text. The basic rotational bands are constructed from the intrinsic states by using the condition of the angular momentum constraint and cross each other without mixing of the intrinsic states caused by rotation. The real rotational band bearing all of the effects of rotation is obtained by diagonalizing the Hamiltonian of the particle-rotor model rotating about the x-axis by using the states with the same angular momentum of the basic rotational bands. In the diagonalization, the basic zero-quasiparticle band and the lowest basic one-quasiparticle one-quasihole band are used. The resulting yrast band shows clearly the backbending.
