    "abstract": "We explore isospin mixing beyond that due to the Coulomb interaction in the\nframework of an exactly solvable microscopic sp(4) algebraic approach.\nSpecifically, we focus on the isospin non-conserving part of the pure nuclear\npairing interaction. The outcome of this study shows the significance of the\npairing charge dependence and its role in mixing isospin multiplets of\npairing-governed isobaric analog 0+ states in light and medium mass nuclei,\nespecially in nuclei with equal numbers of protons and neutrons. The model\nreveals possible, but still extremely weak, non-analog beta-decay transitions\nand estimates their relative strengths within a shell closure.",
