    "abstract": "A study of the energies of the first excited $0^+$ states in all even-even\n$Z$ $\\geq$ 8 nuclei reveals an anomalous behavior in some nuclei with $N$ =\n$Z$, $Z$ $\\pm$ 2. We analyze these irregularities in the framework of the shell\nmodel. It is shown that proton-neutron correlations play an important role in\nthis phenomenon.",
