“…Gamma-ray spectroscopy measurements of the deformed nucleus 174 Lu have been carried out previously using the 170 Er( 7 Li,3n) [11] and 176 Yb(p,3n) [12][13][14][15][16] reactions, where many two-quasiparticle structures, up to spins of ∼15h, were populated. However, the proximity of 174 Lu to the stability line limits the possibilities of populating this nucleus to high spin with conventional reactions.…”

Multi-quasiparticle isomers inLu174

Four-, six-, and eight-quasiparticle isomers with K π = 14 − , (21 + ) and (26 − ) have been identified in the deformed nucleus 174 Lu, in addition to the previously reported K π = 13 + , four-quasiparticle isomeric state.Analysis of alignments and in-band crossover-to-cascade branching ratios lead to the characterization of the configurations associated with the K π = 14 − and (21 + ) isomers. The excitation energies of the observed states are compared with results from multi-quasiparticle calculations that include effects of blocking and residual nucleon-nucleon interactions. Good agreement is found for medium-spin (I = 13-14h) and the highest spin (I > 20h) states observed, but there remain ambiguities in assigning configurations in the I = 15-19h region.

“…With the development of experimental techniques, more and more measurements have been done for the neutron rich nuclei. As for the neutron rich doubly-odd Lu nuclei, many experiments have been performed not only for the 2-quasiparticle (qp) structures, but also for the high-K multi-qp isomers [21][22][23][24][25][26][27][28][29]. * Supported by NSFC (Grant No.…”

Two-quasiparticle bands and low-lying excited high-K four-, six-, and eight-quasiparticle bands in the doubly-odd 174,176 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 174,176 Lu are taken from the adjacent odd-A Lu and Hf isotopes, which are adopted to reproduce the experimental bandhead energies of the one-quasiproton and one-quasineutron bands of these odd-A Lu and Hf nuclei, respectively. Once the quasiparticle configurations are determined, the experimental bandhead energies and the moments of inertia of these two-and multiquasiparticle bands are well reproduced by PNC-CSM calculations. The Coriolis mixing of the low-K (K = |Ω1 −Ω2|) two-quasiparticle band of the Gallagher-Moszkowski doublet with one nucleon in the Ω = 1/2 orbital is analyzed.
