    "abstract": "We present ab initio perturbed ion calculations on the structures and\nrelative stabilities of doubly charged [(NaCl)_m(Na)_2]2+ cluster ions. The\nobtained stabilities show excellent agreement with experimental abundances\nobtained from mass spectra. Those enhanced stabilities are found to be a\nconsequence of highly compact structures that can be built only for certain\nvalues of m. Nearly all magic number clusters can be shown to be constructed in\none of the two following ways: (a) by adding tri- or penta-atomic chains to two\nedges of a perfect neutral (NaCl)_n cuboid, with n=m-2 or n=m-4, respectively;\n(b) by removing a chloride anion from a perfect singly charged (NaCl)_nNa+\ncuboid, with n=m+1.",
