Abstract: (APS)
This paper presents the results of a calculation of the electromagnetic radii of nucleons predicated on the assumption of vector dominance for the hadronic electromagnetic current. Vector dominance is implemented through the use of field-current identities. A new feature of this work is an attempt, for the isovector radii, to take account of the structure of the ρ-nucleon vertex. While the numerical results are somewhat model-dependent, they do lend support to the view that the radii are determined by the low-energy dynamics of the meson-nucleon system.- nucleon: form factor
