Abstract

The yrast spectra of the nuclides 68 ≦ Z ≦ 70, 89 ≦ N ≦ 99 are analysed in terms of quasiparticle configurations in a deformed field rotating with the frequency ω. The excitation energy, e', in the rotating frame (Routhian) and the aligned angular momentum, i, relative to the ground state band as functions of ω are extracted from the experimental rotational bands which are classified with respect to their signature, α, and parity, π. These experimental quantities are compared with the ones calculated from the quasiparticle level diagrams. Phenomena like backbending and the occurrence of aligned bands in both even-even and odd-mass nuclei and their mutual relationship are interpreted in terms of quasiparticle configurations that may cross each other with increasing frequency.

Prediction of novel effects in rotational nuclei at high speed
2024, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The study of high-speed rotating matter is a crucial research topic in physics due to the emergence of novel phenomena. In this letter, we combined cranking covariant density functional theory (CDFT) with a similarity renormalization group approach to decompose the Hamiltonian from the cranking CDFT into different Hermite components, including the non-relativistic term, the dynamical term, the spin-orbit coupling, and the Darwin term. Especially, we obtained the rotational term, the term relating to Zeeman-like effect, and the spin-rotation coupling due to consideration of rotation and spatial component of vector potential. By exploring these operators, we aim to identify novel phenomena that may occur in rotating nuclei. Signature splitting, Zeeman-like effect, and spin-rotation coupling are among the potential novelties that may arise in rotating nuclei. Additionally, we investigated the observability of these phenomena and their dependence on various factors such as nuclear deformation, rotational angular velocity, and magnetic field-like strength.
Pairing effect on critical spin in chiral rotation
2024, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The critical spin $I_{c}$ (or critical frequency $ħ ω_{c}$ ) represents the minimum spin (or rotational frequency) required for stable chiral solutions in nuclear systems. The effect of pairing on the critical spin has been examined for the particle-hole configuration $π (1 h_{11 / 2}) \otimes ν {(1 h_{11 / 2})}^{- 1}$ with a triaxial deformation parameter of $γ = 30^{\circ}$ using the particle rotor model, which treats the total angular momentum as a good quantum number. Increasing pairing interaction keeps the critical spin $I_{c}$ constant, but decreases the critical rotational frequency $ħ ω_{c}$ . This is due to that the enhanced pairing interaction causes valence nucleons angular momenta to align preferentially along the medium axis, resulting in a larger effective collective moment of inertia and facilitating the emergence of chiral rotation at a lower frequency. However, even with an increase in pairing gap from 0.0 to $2.0 MeV$ , the resulting increase in medium axis alignment is less than 1ħ, which is insufficient to change the value of the critical spin $I_{c}$ . This study suggests that the critical spin remains robust against the influence of pairing interaction.
Nuclear Structure and Decay Data for A=167 Isobars
2023, Nuclear Data Sheets
Experimental nuclear spectroscopic data are compiled and evaluated for 17 known nuclides of mass 167 (Sm, Eu, Gd, Tb, Dy, Ho, Er Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt), 23 years after the previous full evaluation by 2000Ba65. Detailed information is presented for each reaction and decay experiment. Combining all the available data, recommended values are provided for energies, spins and parities, and half-lives of levels, with energies, branching ratios and multipolarities of γ radiations, and characteristics of β and α radiations in radioactive decays. The α decays of A=171 nuclei to A=167 daughters are included in this work, while for α decays of A=167 nuclei to A=163 daughters, consult Nuclear Data Sheets (2010Re03) or the ENSDF database for A=163. ¹⁶⁷Er, ¹⁶⁷Tm, ¹⁶⁷Yb, ¹⁶⁷Lu and ¹⁶⁷Ta are among the most extensively studied nuclides via decay and high-spin gamma-ray spectroscopy measurements, followed by ¹⁶⁷Ho, ¹⁶⁷Hf, ¹⁶⁷W, and ¹⁶⁷Os. Information for excited states in ¹⁶⁷Dy, ¹⁶⁷Re, and ¹⁶⁷Ir are limited; no excited states have yet been identified in ¹⁶⁷Sm, ¹⁶⁷Eu, ¹⁶⁷Gd, ¹⁶⁷Tb and ¹⁶⁷Pt, with the ground-state half-life of ¹⁶⁷Sm remaining unknown. This work supersedes the earlier evaluation of A=167 nuclei by 2000Ba65.
Study of normal deformed bands in light Lutetium isotopes
2023, Nuclear Physics A
The projected shell model has been employed to study the energy levels and alignment frequencies of the normally deformed bands of light lutetium isotopes. Band head spins and configurations have been reproduced for all the positive parity bands of ^161−165Lu isotopes and negative parity bands of ¹⁶³Lu. The theoretical aligned angular momenta reasonably reproduced the observed backbends and their corresponding rotational frequencies for all the experimentally observed normally deformed bands. Moreover, I = 7/2⁻ state is predicted as band head spin for negative parity yrast bands of ^161,165Lu. The negative parity yrast bands of ^161,165Lu are predicted to have 1π1h_11/2[523]7/2⁻ configuration. Further, the calculated B(E2) values of ¹⁶⁵Lu show reasonable agreement with the available experimental data. The dip predicted in the B(E2) values may be interpreted due to the alignment of a pair of neutrons in the neutron $1 i_{13 / 2}$ orbital of all yrast bands of ^161−165Lu.
Hydrogen-adsorbed group-IV materials
2023, Fundamental Physicochemical Properties of Germanene-related Materials
Hydrogenations of monolayer group-IV systems clearly present the diverse quasiparticle phenomena in this chapter. The rich crystal symmetries are directly reflected in the planar or buckled honeycomb lattice, IV–IV bond lengths, their observable fluctuations, IV–H bonding angles, H-adatom hollow sites and heights. These featured geometries, which are largely enhanced by the various chemisorption cases, have successfully created the unique band structures, wave functions, spatial charge density distributions/their variations after hydrogenations, as well as, van Hove singularities. Optical properties, transverse dielectric functions, energy loss spectra, absorption coefficients and reflectance spectra, and absorption coefficients, clearly show the unusual interband electron-hole excitations and coherent carrier oscillations, in which the different plasmon modes come to exist in the specific energy ranges. The pronounced absorption peaks and excitonic effects are successfully combined with the joint van Hove singularities. Each prominent structure is thoroughly examined to be a special set of orbital hybridizations from the initial and final band-edge states. The lowest/lower excitonic peaks are due to the stable or quasi-stable electron-hole bound states. The red shifts of threshold absorption frequency indicates the fact that optical gaps are less than energy gaps.
Systematic investigation of the high-spin structures in the odd-odd nuclei <sup>166,168,170,172</sup>Re by a particle-number conserving method
2021, Nuclear Physics A
The recently observed two and four-quasiparticle high-spin rotational bands in the odd-odd nuclei ^{166,168,170,172}Re are investigated using the cranked shell model with pairing correlations treated by a particle-number conserving method. The experimental moments of inertia and alignments can be reproduced well by the present calculation if appropriate bandhead spins and configurations are assigned for these bands, which in turn confirms their spin and configuration assignments. It is found that the bandhead spins of those two rotational bands observed in ¹⁶⁶Re (Li et al., 2015) [8] should be both increased by 2ħ to get in consistent with the systematics of the experimental and calculated moments of inertia for the same configurations in ^168,170,172Re. The variations of the backbendings/upbendings with increasing neutron number in these nuclei are investigated. The level crossing mechanism is well understood by analyzing the variations of the occupation probabilities of the single-particle states close to the Fermi surface and their contributions to the angular momentum alignment with rotational frequency. In addition, the influence of the deformation driving effects of the proton $1 / 2^{-} [541]$ ( $h_{9 / 2}$ ) orbital on the level crossing in ¹⁷²Re is also discussed.
