Abstract

In the frame of a thorough investigation of activation cross sections of deuteron induced nuclear reactions, excitation functions on iridium were investigated up to 50 MeV deuteron energy. Production cross sections were measured for the 193mPt, 191Pt, 189Pt, 188Pt, 187Pt, 194m2Ir, 194gIr(m1 + ), 192gIr(m1 + ), 190m2Ir, 190gIr(m1 + ), 189Ir, 188Ir, 187Ir and 191gOs(m1 + ) radionuclides. Activation method, stacked foil irradiation technique and off-line gamma-ray spectrometry were used for quantification of the radionuclides. The experimental results are compared with earlier data in the overlapping energy range. We discuss theoretical predictions obtained from the ALICE-IPPE-D and EMPIRE-II-D codes. The experimental data are also compared with calculated values reported in the TENDL-2017 on-line library calculated by using the TALYS code.
