“…Figure 2 presents a partial level scheme established from the present data. This scheme agrees with the results of O'Neil and Burke [6] who have given the configuration assignments. The precise energy of the first two excited states of the ground-state band was already known from studies of the 170.8-keV isomeric-state decay [7].…”

“…2 The multipolarity of the 129.066-keV transition has to be El, because the larger internal conversion coefficient for any other multipolarity would make the feeding of the 111.76-keV level exceed the outgoing intensity. This is consistent with the orbital assignment proposed in [6]. In a note on 17+Lu, Andr6 and Foin [14] have proposed the decay scheme of the 7+7 state shown in Fig.…”

“…We expect it will be especially rewarding to combine results from various experimental approaches. The nucleus 174Lu is a particularly interesting case because many levels have been established by neutron [5,6] and proton [6] transferreaction spectroscopy. Nuclei which can be populated using transfer reactions are not very neutron deficient since the targets are made from stable isotopes.…”

Levels in 174Lu have been investigated using the 176yb(p, 3n) reaction. Prompt and delayed 7-ray spectra have been observed with a 0.56-cm 3 Ge(Li) detector by a multispectrum analysis method. The half-life and decay mode of two isomeric levels, one at 240.8keV (395_15ns) and the other at 365.1keV (145+_3ns) have been firmly established. Hindrance factors are discussed. New delayed transitions in 175Lu are also noted.

“…It is well known that when one of the nucleons is in an Ω = 1/2 orbital, the GM doublet has ∆K = 1, accordingly the two bands are expected to be Coriolis admixed. This effect can be very significant in the K < band, which has been identified in the odd-odd rare-earth nuclei [114,115]. The similar MOI's in the K π = 1 − and 2 − bands may be from this mixing and need further exploration both experimentally and theoretically.…”

The rotational bands in nuclei with Z ≈ 100 are investigated systematically by using a 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. By fitting the experimental single-particle spectra in these nuclei, a new set of Nilsson parameters (κ and µ) and deformation parameters (ε2 and ε4) are proposed. The experimental kinematic moments of inertia for the rotational bands in even-even, odd-A and odd-odd nuclei, and the bandhead energies of the 1quasiparticle bands in odd-A nuclei, are reproduced quite well by the PNC-CSM calculations. By analyzing the ω-dependence of the occupation probability of each cranked Nilsson orbital near the Fermi surface and the contributions of valence orbitals in each major shell to the angular momentum alignment, the upbending mechanism in this region is understood clearly.

“…With the development of experimental techniques, more and more measurements have been taken 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].…”

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.
