Dynamical symmetry of isobaric analog 0+ states in medium mass nuclei
arXiv:nucl-th/0703071 · doi:10.1103/PhysRevC.70.064302
Abstract
An algebraic sp(4) shell model is introduced to achieve a deeper understanding and interpretation of the properties of pairing-governed 0+ states in medium mass atomic nuclei. The theory, which embodies the simplicity of a dynamical symmetry approach to nuclear structure, is shown to reproduce the excitation spectra and fine structure effects driven by proton-neutron interactions and isovector pairing correlations across a broad range of nuclei.
