Intrinsic properties of high-spin band structures in triaxial nuclei

Triaxial Black-hole Nuclei

We demonstrate that the nuclei of galaxies containing supermassive black holes can be triaxial in shape. Schwarzschild’s method was first used to construct self-consistent orbital superpositions representing nuclei with axis ratios of 1 : 0.79 : 0.5 and containing a central point mass representing a black hole. Two different density laws were considered, ρ ∝ r−γ , γ = {1, 2}. Only non-chaotic o...

Wobbling motion in triaxial superdeformed nuclei

We discuss some characteristic features of the wobbling motion excited on the triaxial superdeformed Lu nucleus. We show how these features are connected to the moments of inertia microscopically calculated by means of the quasiparticle RPA in the rotating frame.

Orbital Structure of Triaxial Black - Hole Nuclei

Orbital motion in triaxial nuclei with central point masses, representing supermassive black holes, is investigated. The stellar density is assumed to follow a power law, ρ ∝ r −γ , with γ = 1 or γ = 2. At low energies the motion is essentially regular; the major families of orbits are the tubes and the pyramids. Pyramid orbits are similar to box orbits but have their major elongation parallel ...

Rotation of triaxial nuclei: wobbling and chirality

Description of even-even triaxial nuclei within the Coherent State and the Triaxial Rotation Vibration Models

The coherent state model (CSM) and the triaxial rotation-vibration model (TRVM) are alternatively used to describe the ground, γ and β bands of 228Th. CSM is also applied to the nuclei 126Xe and 130Ba, which were recently considered in TRVM. The two models are compared with respect to both their underlying assumptions and to their predicted results for energy levels and E2 branching ratios. Bot...
