Abstract:
An experiment on irradiation of the 197Au isotope by a beam of bremsstrahlung γ-rays of maximum energy Eγm = 70 MeV has been carried out at the RTM-70 race-track microtron of the INP MSU. Residual activity spectra of the irradiated sample were measured. Multiparticle photonuclear reactions on the 197Au nucleus are observed. Photonuclear reactions with emission of as many as six neutrons are observed for the first time.
