摘　　要：Thick gold targets were bombarded with 47 MeV/nucleon C ions and the radioactive isotopes of iridium 12 and platinum were produced through the multi-nucleon transfer reactions. The production cross-sections of iridium isotopes in the reactions have been determined by a combination of radiochemical separation and off-line γ-ray spec- troscopy technique. The obtained Ir isotope distribution was compared with those obtained in other experiment as well as calculated by the statistical model.Thick gold targets were bombarded with 47 MeV/nucleon C ions and the radioactive isotopes of iridium 12 and platinum were produced through the multi-nucleon transfer reactions.
