    "abstract": "An exactly solvable sp(4) algebraic approach extends beyond the traditional\nisospin conserving nuclear interaction to bring forward effects of isospin\nsymmetry breaking and isospin mixing resulting from a two-body nuclear\ninteraction that includes proton-neutron (pn) and like-particle isovector\npairing correlations plus significant isoscalar pn interactions. The model\nyields an estimate for the extent to which isobaric analog 0+ states in light\nand medium mass nuclei may mix with one another and reveals possible, but still\nextremely weak, non-analog beta-decay transitions.",
