摘要Nuclear pairing gaps of normally deformed and superdeformed nuclei are investigated using the particle-number-conserving (PNC) formalism for the cranked shell model, in which the blocking effects are treated exactly. Both rotational frequency omega dependence and seniority (number of unpaired particles) nu dependence of the pairing gap (Delta) over tilde are investigated. For the ground-state bands of even-even nuclei, PNC calculations show that, in general, (Delta) over tilde decreases with increasing omega, but the omega dependence is much weaker than that calculated by the number-projected Hartree-Fock-Bogolyubov approach. For the multiquasiparticle bands (seniority nu > 2), the pairing gaps stay almost omega independent. As a function of the seniority nu, the bandhead pairing gaps (Delta) over tilde(nu, omega = 0) decrease slowly with increasing nu. Even for the highest seniority nu bands identified so far, (Delta) over tilde(nu, omega = 0) remains greater than 70% of (Delta) over tilde(nu = 0, omega = 0).
