Abstract

We report the calculation of electromagnetic form factors of nucleons within a relativistic three-quark model with Gaussian shape for the nucleon-quark vertex. The allowed region for two adjustable parameters, the range parameter Λ_N in the Gaussian and the constituent quark mass m_q, is obtained from fitting the data for magnetic moments and electromagnetic radii of nucleons. The shapes of electric and magnetic nucleon form factors calculated in this approach with the central parameters m_q=420 MeV and Λ_N=1.25 GeV are close to the data for momentum transfers 0≤ Q²≤ 1 GeV²
