Elastic Form Factors in Point-form Approach
  Using the point-form approach to relativistic quantum mechanics, a covariant framework is presented for the calculation of proton and neutron electromagnetic form factors. Results for charge radii, magnetic moments, and electric as well as magnetic form factors are produced using the wave functions obtained in the so-called Goldstone-boson-exchange constituent quark model. All the predictions are found in remarkable agreement with existing experimental data.
