摘要

In the frame of an IAEA coordinated research project (CRP) on nuclear data for production of therapeutic radionuclides, the production of ¹⁹²Ir via deuteron-induced reactions on enriched ¹⁹²Os was investigated up to 21 MeV deuteron energy. Cross sections were measured using the conventional stacked-foil irradiation technique and high-resolution gamma-ray spectroscopy of the activation products. No earlier experimental data were found in the literature. The excitation functions of the ¹⁹²Os(d,2n)^192m1+gIr and ¹⁹²Os(d,p)¹⁹³Os reactions were compared with the results of nuclear model calculations using the standard and presently upgraded versions (D-version) of ALICE-IPPE, EMPIRE-II and GNASH codes, while for the (d,2n) channel the GNASH and EMPIRE-II codes reproduced the data in an acceptable way; in both cases for the (d,p) reaction the very large discrepancy observed between the experimental data and standard codes results is vanishing when the upgraded versions of ALICE and EMPIRE-II are used. A comparison of the reactor and cyclotron production routes of ¹⁹²Ir is given.
