Cusps and Triaxiality
Statler (1987) demonstrated that self-consistent triaxial models with the perfect density law could be constructed for virtually any choice of axis ratios. His experiments are repeated here using triaxial mass models based on Jaffe's density law, which has a central density that diverges as r −2 , similar to what is observed in low-luminosity elliptical galaxies. Most of the boxlike orbits are ...
متن کاملTriaxiality and shape coexistence in Germanium isotopes
The ground-state deformations of the Ge isotopes are investigated in the framework of GognyHartree-Fock-Bogoliubov (HFB) and Skyrme Hartree-Fock plus pairing in the BCS approximation. Three different Skyrme parametrizations are used to explore the influence of different effective masses and spin-orbit models. There is generally good agreement for binding energies and deformations (total quadrup...

متن کاملSe p 19 99 Triaxiality in 48 Cr
Rotational behavior inducing triaxiality is discussed for Cr in the cranked NilssonStrutinsky (CNS) model, as well as in the spherical shell model. It is shown that the low-spin region up to about I=8, has a prolate well-deformed shape. At higher spins the shape is triaxial with a “negative-γ” deformation, that is, with rotation around the classically forbidden intermediate axis. By comparing c...
