The contribution of the diffraction dissociation of an impinging proton in cosmic ray interactions accompanied by the formation of a small number of high-energy gamma-quanta with energies less than 100 TeV is investigated. The diffraction dissociation cross section of the impinging protons are calculated for proton-proton interactions at the energy interval 10 to 100 TeV to represent approximately 27% of the total interaction cross section, with an average of 2.4 and 2.6 neutral pions formed at energies of 10 and 100 TeV, respectively. An examination of measurements of 137 elementary act-type cosmic ray interactions at energies from 3 to 30 TeV obtained by an ionization calorimeter and an X-ray chamber reveals, however, that more high-energy gamma-ray-containing interactions are present than can be accounted for by the diffraction dissociation of nucleons into large masses.
