    "abstract": "The sensitivity of the deuteron form factor to contributions from the excited\nstates of the nucleon is explored using a simple model of the nucleon-nucleon\ninteraction which employs a tower of charged nucleon resonances. The model is\nmanifestly covariant, analytically solvable, and gauge invariant. The\nconsequences of this model are studied in the simplest possible framework. We\nassume that all particles have spin zero and that the tower has only three\ncharged members, which consist of the proton, the Roper, and a higher state in\nthe vicinity of the $D_{13}$. Nucleon-nucleon S-wave phase shifts and the\ndeuteron form factor are calculated using this three member tower, and the\nresults are compared to similar calculations using the proton ground state\nonly. We conclude that the deuteron form factor is insensitive to the presence\nof excited states of the proton unless those states are of sufficiently low\nmass to produce strong inelasticities in $NN$ scattering channels.",
