Particle-number conserving analysis of the moments of inertia of high- K multiquasiparticle bands in 179Ta

Abstract

The experimental one-, three-, and five-quasiparticle bands in 179Ta are analyzed by the particle-number conserving (PNC) method for the cranked shell model with pairing interaction, in which the particle-number is conserved and the blocking effects are considered exactly. Once the quasiparticle configurations, particularly those of the high- K three- and five-quasiparticle bands, are determined, the experimental moments of inertia and their variations with rotational frequencies can be reproduced very well by PNC calculations without any free parameter.
