High-energy elastic hadron collisions and space structure of hadrons
  The elastic and inelastic profiles have been derived from the measured elastic differential cross section data with the help of exact impact parameter representation of elastic scattering amplitude. The results obtained for $pp$ scattering at energy of 53 GeV and $\bar{p} p$ scattering at energy of 541 GeV have been presented. They indicate that nucleons can be regarded as objects characterized by a small core (diameter $\sim$ 0.4$\div$0.8 fm) and a half transparent outer shell (responsible mainly for elastic hadron scattering).
