Abstract：
Using the particle-number conserving (PNC) method for treating the cranked shell model,the microscopic mechanism of the variation with rotational frequency ω of the kinematics moments of inertia for the rare-earth deformed nuclei ^178,179Hf is investigated. The 2-qp and 4-qp bands in ¹⁷⁸₇₂Hf and 3-qp bands in ¹⁷⁹₇₂Hf are analyzed and calculated.The observed ω variation of J⁽¹⁾ is reproduced satisfactorily in PNC calculations. Our analysis shows that the difference between the ω variations of J⁽¹⁾ for the high K multi-quasiparticle bands and for the ground state band is mainly due to the Pauli blocking effects of high j intruder orbitals near the Fermi surface.
