    "abstract": "A simple superfluid model with an effective four body interaction of monopole\npairing type is used to explain the staggering of the charge radii in the\nisotope chains. The contribution of deformation and of the particle number\nprojection are analyzed for the Sn isotopes. Good results are obtained for the\nstaggering parameters and neutron pairing energies.",
