Abstract

A Fermi-aligned $(i_{132})^{2}$ rotational band, with K≈8, has been observed in an even-even nucleus, ¹⁸⁰W. Its structure corresponds to a t-band in the tilted-cranking representation. It crosses the ground-state band at $I = 16 h ̵$ , giving rise to backbending in the yrast sequence. Contrary to the usual interpretation, backbending in this case is not caused by the s-band. Comparison is made with other possible t-band crossings in the A ≈ 180 region.

Diversity of shapes and rotations in the γ-soft 130Ba nucleus: First observation of a t-band in the A = 130 mass region
2019, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Several new bands have been identified in ¹³⁰Ba, among which there is one with band-head spin $8^{+}$ . Its properties are in agreement with the Fermi-aligned $ν h_{11 / 2}^{2}$ , $7 / 2^{-} [523] \otimes 9 / 2^{-} [514]$ Nilsson configuration. This is the first observation of a two-quasiparticle t-band in the $A = 130$ mass region. The t-band is fed by a dipole band involving two additional $h_{11 / 2}$ protons. The odd-spin partners of the proton and neutron S-bands and the ground-state band at high spins are also newly identified. The observed bands are discussed using several theoretical models, total Routhians surfaces (TRS), tilted axis cranking (TAC), particle rotor model (PRM) and projected shell model (PSM), which strongly suggest the coexistence of prolate and oblate shapes polarized by rotation aligned two-proton and two-neutron configurations, as well as prolate collective rotations around axes with different orientations. With the new results, ¹³⁰Ba presents one of the best and most complete sets of collective excitations that a γ-soft nucleus can manifest at medium and high spins, revealing a diversity of shapes and rotations for the nuclei in the $A = 130$ mass region.
Configurations and hindered decays of K isomers in deformed nuclei with A > 100
2015, Atomic Data and Nuclear Data Tables
Spectroscopic information on the decay properties of high- $K$ isomers in deformed and transitional nuclei has been evaluated and collated. Assigned multi-quasiparticle configurations are included. Factors that control the transitions strengths, such as various contributions to $K$ mixing, are outlined. The systematics of $K$ -forbidden transitions for different multipolarities are discussed for selected cases in terms of the hindrances, $F_{W}$ , and of the reduced hindrance factor per degree of $K$ forbiddenness, $f_{ν}$ , where $ν = | Δ K - λ |$ , $Δ K$ is the $K$ -value difference between the initial and final state and $λ$ is the transition multipole order. With the improved statistics for $E 1$ , $M 1$ and $E 2$ transitions, a factorization into the product of the underlying multipolarity-dependent transition strength and a $ν$ -dependence, due to $K$ forbiddenness ( $f_{0}$ ), is possible. This suggests a weaker dependence on $K$ forbiddenness than is commonly assumed.

Evaluated spectroscopic data for all nuclei with mass number A=180 and corresponding level schemes from radioactive decay and reaction studies are presented. This evaluation contains new data on ¹⁸⁰Ta from (p,nγ) and (d,2nγ) work; data on ¹⁸⁰Ta, ¹⁸⁰W, ¹⁸⁰Ir and ¹⁸⁰Hg from heavy-ion γ-ray measurements, and band structures; and data on ¹⁸⁰Os and ¹⁸⁰Os from ε-decays. The present evaluation supersedes the earlier one by E. Browne (1994Br17), published in Nuclear Data Sheets 71, 81 (1994).
Competing phenomena: High-seniority excitations and γ-softness in 184Os
2002, Nuclear Physics A
The nuclear structure of the stable nucleus ¹⁸⁴₇₆Os has been studied including five newly identified rotational bands built on 2-quasiparticle K^π=0⁺, 6⁻, 8⁻ couplings. The excitation energies of the proposed multi-quasiparticle excitations are in good agreement with predictions of blocked BCS calculations. The interaction responsible for the first band crossing, caused by a high-K tilted 2-neutron configuration, is calculated and a new interpretation presented for the yrast states after the interaction. A second crossing with an aligned s–β band is also reported. The yrast behaviour at high spins is dominated by a wealth of short-lived (nanoseconds and shorter) high-K levels. The low reduced hindrances for intrinsic state decays are discussed, and attributed to the triaxial shapes and fluctuations predicted by configuration-constrained potential-energy-surface calculations. Comparisons with neighbouring nuclei are made.
Multi-quasiparticle states and K -forbidden transitions in 183Os
2001, Nuclear Physics A
High-spin states in ¹⁸³Os have been studied using the ¹⁷⁰Er(¹⁸O, 5n) reaction at a beam energy of 85 MeV. Nine rotational bands based on 1-, 3-, 5- and 7-quasiparticle excitations have been observed. Nilsson configurations are assigned for the newly observed bands using g-factors deduced from M1/E2 branching ratios within the bands. In addition, two isomers with K^π=(43/2⁺) and (43/2⁻) have been identified. The K^π=(43/2⁺) isomer decays directly to the K^π=9/2⁺ ground-state band with a large difference in the K quantum number, ΔK=17. The decay rates are discussed in terms of a tunneling model where high-K (isomeric) and low-K states interact via fluctuations towards triaxial nuclear shapes.
