Particle-number conserving analysis for the 2-quasiparticle and high- multi-quasiparticle states in doubly-odd Lu
Two-quasiparticle bands and low-lying excited high- four-, six-, and
eight-quasiparticle bands in the doubly-odd Lu are analyzed by
using the cranked shell model (CSM) with the pairing correlations treated by a
particle-number conserving (PNC) method, in which the blocking effects are
taken into account exactly. The proton and neutron Nilsson level schemes for
Lu are taken from the adjacent odd- Lu and Hf isotopes, which
are adopted to reproduce the experimental bandhead energies of the
one-quasiproton and one-quasineutron bands of these odd- Lu and Hf nuclei,
respectively. Once the quasiparticle configurations are determined, the
experimental bandhead energies and the moments of inertia of these two- and
multi-quasiparticle bands are well reproduced by PNC-CSM calculations. The
Coriolis mixing of the low- () two-quasiparticle band
of the Gallagher-Moszkowski doublet with one nucleon in the
orbital is analyzed.Comment: 8 pages, 5 figures, 2 tables, to be published at Chinese Physics
