Popis: The thallium isotopes 203Tl and 205Tl were irradiated using a beam of bremsstrahlung gamma quanta with the maximum energy E γ m = 50 MeV from an RTM-70 electron racetrack microtron installed at the Scobeltsyn Nuclear Physics Research Institute (Lomonosov Moscow State University, Russia). The gamma spectra of the residual activity were measured for an irradiated sample. Photonuclear reactions in the 203Tl nuclei with emission from one to four neutrons were observed experimentally. The relative yields of the reactions 203Tl(γ,n)202Tl, 203Tl(γ,2n)201Tl, 203Tl(γ,3n)200Tl, and 203Tl(γ,4n)199Tl were determined for the first time.
