摘要：

Neutron-proton pair knocking-out by photons from iron (Fe-56) nuclei is studied by measuring induced gamma activity of Mn-54 isotope. Experiments are performed in a synchrotron beam at two maximum photon energies, 150 and 650 MeV. It was found that the yield of the reaction under study at the maximum energy of 150 MeV is almost zero, whereas a significant yield of gamma active Mn-54 nuclei is measured at the energy of 650 MeV. The cross section of the neutron-proton pair production reaction on Fe-56 at an energy of 650 MeV is estimated as 4 center dot 10(-27) cm(2).
