Time-odd components in the mean field of rotating superdeformed nuclei.
Rotation-induced time-odd components in the nuclear mean field are analyzed using the Hartree-Fock cranking approach with effective interactions SIII, SkM*, and SkP. Identical dynamical moments J (2) are obtained for pairs of superdeformed bands 151 Tb(2)– 152 Dy(1) and 150 Gd(2)– 151 Tb(1). The corresponding relative alignments strongly depend on which time-odd mean-field terms are taken into ...
متن کاملTime-odd Components in the Rotating Mean Field and Identical Bands
A systematic construction of the energy-density functional within the local density approximation is presented. The Hartree-Fock equations corresponding to such a functional are solved in case of rotating superde-formed nuclei. The identical bands in 152 Dy, 151 Tb, and 150 Gd are investigated and the time-odd components in the rotating mean field are analyzed.
متن کاملGeneral Relativistic Mean Field Theory for Rotating Nuclei
We formulate a general relativistic mean field theory for rotating nuclei starting from the special relativistic σ-ω model Lagrangian. The tetrad formalism is adopted to generalize the model to the accelerated frame.
متن کاملRotating Nuclei at Extreme Conditions: Cranked Relativistic Mean Field Description
CRMF theory [1,2] represents the extension of relativistic mean field (RMF) theory to the rotating frame and thus provides a natural framework for the description of rotating nuclei at high spin. Available experimental data on rotating nuclei at extreme conditions of large deformation (superdeformation) and fast rotation in different mass regions allow to test the theoretical models (in our cas...
متن کاملRestoration of the Broken D2-symmetry in the Mean Field Description of Rotating Nuclei
Signature effects observed in rotational bands are a consequence of an inherent D2-symmetry. This symmetry is naturally broken by the mean field cranking approximation when a tilted (non-principal) axis orientation of the nuclear spin becomes stable. The possible tunneling forth and back between the two symmetry-related minima in the double-humped potential-energy surface appears as a typical b...
