[en] Inclusive emission of protons from the reaction h+A→p/Qsub(p)>90 deg, Tsub(p)>30 MeV/ + anything is investigated. A model describing the fast proton emission in the bach hemisphere in hadron-nucleus interactions has been considered. Representations about anomalously high momenta or nucleon densities in the ground state of target-nucleus are not used in the model. In the framework of the model the proton emission results from the decay of fewnucleon groups of target-nucleus highly excited in the quasi-diffraction hadron scattering from these groups. Considered is a hypothesis of universality of the fewnucleon group excitation function for excitations of the order of the pion mass and higher
