Partial Dynamical Symmetry and Anharmonicity in Gamma-Soft Nuclei

TL;DR

This paper demonstrates that partial dynamical symmetry effectively describes anharmonicity in excited nuclear bands of $^{196}$Pt while preserving solvability and symmetry in the ground state.

Contribution

It introduces the application of partial dynamical symmetry to model anharmonicity in gamma-soft nuclei, maintaining solvability and symmetry in the ground band.

Findings

Partial dynamical symmetry models anharmonicity in $^{196}$Pt.

Ground band retains SO(6) symmetry and solvability.

Excited bands exhibit anharmonic behavior.

Abstract

Partial dynamical symmetry is shown to be relevant for describing the anharmonicity of excited bands in $^{196}$Pt while retaining solvability and good SO(6) symmetry for the ground band.
