Description

We estimate the two-photon exchange corrections to both proton and neutron electromagnetic physical observables in a relativistic light cone quark model. At a fixed Q2 the corrections are found to be small in magnitudes, but strongly dependent on scattering angle. Our results are comparable to those obtained from simple hadronic model in the medium momentum transfer region.
