Vector-Meson Fit to Nucleon Form Factors

Available data on nucleon electric and magnetic form factors have been fitted with a dispersion theoretic formula, assuming the electron-nucleon scattering process dominated by the $\rho$, $\omega$, and $\phi$ mesons and hard cores. The data are found to fit a smooth curve of the assumed form. The fit, based mainly on proton data, predicts neutron form factors compatible with experimental results.
