Partial Dynamical Symmetry in Deformed Nuclei.
We discuss the notion of partial dynamical symmetry in relation to nuclear spectroscopy. Explicit forms of Hamiltonians with partial SU(3) symmetry are presented in the framework of the interacting boson model of nuclei. An analysis of the resulting spectrum and electromagnetic transitions demonstrates the relevance of such partial symmetry to the spectroscopy of axially deformed nuclei. PACS n...
متن کاملGeneralized partial dynamical symmetry in nuclei.
We introduce the notion of a generalized partial dynamical-symmetry for which part of the eigenstates have part of the dynamical symmetry. This general concept is illustrated with the example of Hamiltonians with a partial dynamical O(6) symmetry in the framework of the interacting boson model. The resulting spectrum and electromagnetic transitions are compared with empirical data in 162Dy.
متن کاملPartial Dynamical Symmetry and Anharmonicity in Gamma-Soft Nuclei
Partial dynamical symmetry is shown to be relevant for describing the anharmonicity of excited bands in 196Pt while retaining solvability and good SO(6) symmetry for the ground band.
متن کاملNuclei with Tetrahedral Symmetry
Received Revised We discuss a point-group-theory based method of searching for new regions of nuclear stability. We illustrate the related strategy with realistic calculations employing the tetrahedral and the octahedral point groups. In particular, several nuclei in the Rare Earth region appear as excellent candidates to study the new mechanism.
متن کاملChiral Symmetry in Nuclei
The impact of chiral symmetry on nuclear physics is discussed in the context of recent advances in the few-nucleon systems and of dimensional power counting. The tractability of few-nucleon calculations, illustrated by very recent solutions for A = 2 − 6, is shown to follow from power counting based on chiral Lagrangians. The latter predicts the suppression of N -body forces, as originally show...
