Specifically, the recently observed Kπ = 4- bands in 168,170,172Er have been found to experience a configuration change in our calculation. Some other multi-quasiparticle states with uncertain configuration assignments have been reinvestigated by calculating their collective rotations. The configuration-constrained TRS calculation can reproduce experimental data consistently.展开更多

The pairing-deformation-frequency self-consistent TRS calculations repro- duced reasonably the experimental moments of inertia extracted from spectroscopic data. It is calculated that, in these largely elongated (β2 ≈0.65 and β4≈ 0.03) fission isomers, the ν1/2-[981] neutron and π1/2+[651] proton align simultaneously at rotational frequency hω≈0.4 - 0.6 MeV (corresponding to spin I≈80h), which leads to clear upbending in moments of inertia (MoI's). Our calculations have indicated that the hexadecapole deformation f14 influenced significantly the frequency of the rotational alignment of the proton 1/2+[651] orbit.展开更多
