  The generalized parton distributions (GPDs) of the meson and nucleon at small
and large values of the momentum transfer were determined on the basis of the
comparative analysis of different sets of experimental data of electromagnetic
form factors of the proton and neutron, using the different sets of the parton
distribution functions (PDFs). As a result, different form factors of the
nucleons and meson were calculated. The t-dependence of these form factors was
checked up in the description of the nucleon-nucleon and meson-nucleon elastic
scattering and the differential cross sections of the real Compton scattering.
