SU(3) symmetry and scissors mode vibrations in nuclei

  title={SU(3) symmetry and scissors mode vibrations in nuclei},

  journal={Nuclear Physics},
Abstract We show that a nearly perfect SU (3) symmetry emerges from an extended projected shell model. Starting from a deformed potential we construct separate bases for neutron and proton collective rotational states by exact angular momentum projection. These rotational states are then coupled by diagonalizing a residual pairing plus quadrupole interaction. The states obtained exhibit a one-to-one correspondence with an SU (3) spectrum up to high angular momentum and excitation, and their…

Coupled SU(3) models of rotational states in nuclei and quasi-dynamical symmetry
Abstract This paper reports a first step towards the development of a model of low-lying nuclear collective states based on the progression from weak to strong coupling of a combination of systems in
The nuclear scissors mode in a solvable model
Abstract The coupled dynamics of the scissors mode and the isovector giant quadrupole resonance is studied in a model with separable quadrupole-quadrupole residual interactions. The method of Wigner
Multishell shell model for heavy nuclei
Performing a shell-model calculation for heavy nuclei has been a long-standing problem in nuclear physics. Here, we propose one possible solution. The central idea of this proposal is to combine the
Basis-dependent measures and analysis uncertainties in nuclear chaoticity
Abstract Chaoticity in nuclei is usually measured by the information entropy through analyzing wave functions, or by spectral statistics with the spectral rigidity and the nearest neighbor level
The projected shell model (PSM) in its original version is an efficient shell model truncation scheme for well deformed nuclei. However, the model is applicable only to rotational motion, but not
Shell-like quarteting in heavy nuclei: Algebraic approaches based on the pseudo- and proxy-SU(3) schemes
Background: The semimicroscopic algebraic quartet model (SAQM) generates the excitation spectra of shell-like quartets, formed by two protons and two neutrons in a well-defined shell configuration.
Algebraic models for shell-like quarteting of nucleons
Abstract Algebraic models are proposed for the description of the shell-like quarteting of the nucleons both on the phenomenologic and on the semimicroscopic levels. In the former one the quartet is
Implications of deformation and shape coexistence for the nuclear shell model.
Criteria for identifying the shell-model configurations appropriate for describing bands of states for which the sequential filling of single-particle energy levels of the spherical shell model are not respected is proposed.
Probing the E2 properties of the scissors mode with real photons

Analyses of β −Bands of 230,232 Th and 232,234 U by the Projected Shell Model
The ground bands and β-bands of four nuclei 230,232Th and 232,234U in the actinide region are investigated by introducing a collective D0 pair into the projected shell model. We discuss the


Scissors-Mode Vibrations and the Emergence of SU(3) Symmetry from the Projected Deformed Mean Field
Starting from a deformed potential we construct separate bases of collective neutron and proton rotational states by exact angular momentum projection. These rotational states are then coupled by
The quadrupole collectivity and possible existence of macroscopic SU(3) symmetry in some collective shell model states
Abstract The shell model eigenfunctions for low-lying states of 56 Fe and 54 Cr are analyzed to illustrate that the “collective” states of these nuclei can be described as the coupling of a small
The splitting of giant multipole states of deformed nuclei
Abstract A vibrating potential model is applied to deformed nuclei with a deformed harmonic oscillator potential in order to discuss the splitting of isoscalar giant quadrupole states.
Search for a coupling scheme in heavy deformed nuclei: The pseudo SU(3) model
To test the possible usefulness of the pseudo SU(3) coupling scheme a few nuclear properties are examined which can be expected to be governed largely by the (lg$d~2d+3s+) part of the proton
