Abstract

An algebraic $s p (4)$ 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.
