PACE4 statistical model code is used to calculate the theoretical nuclear cross section in the production processes of 125I, 62Zn, 15O and 103Pd, while experimentally decoded nuclear cross sections data of these radionuclide were taken from ENDF(Evaluated nuclear data file) IAEA database, to compute a reliable result, PACE4 statistical model code performed at level density parameter(K=8, K=10 and K=12 ) and the number of cascades(events in monte carlo calculation) is set at 100,000. The target radioisotopes are 124T, 63Cu, 14N and 103Rh are taken for the production of medical useful radioisotope 125I, 62Zn, 15O and 103Pd respectively. Deuteron energies ranging from 4.5MeV to 20MeV were considered for the production of 125I, 17MeV to 35MeV for the production of 62Zn, 1MeV to 20MeV for the production of 15O and energy range from 6.5MeV to 23.5MeV were considered for the production of 103Pd, and then experimental and theoretical outputs of nuclear cross sections of these radionuclide production were analyzed and compared. The maximum experimental and theoretical nuclear cross section computed at different energy range is stated below respectively: for 124T (d,n)125I reaction the maximum cross section at deuteron incident energy of 9.0MeV was 232 mb and 555 mb at 9.5MeV ( at K=12), for 63Cu(d,3n)62Zn reaction 50.5 mb at 33MeV and 63.9 mb at 31.5MeV ( at K=8), for the reaction 14N(d,n)15O the maximum cross section was 213 mb at 3.5MeV and 214 mb at 12.5MeV ( at K=12) and for the reaction 103Rh(d,2n)103Pd the maximum cross section was 1056 mb at 13.5MeV and 1390 mb at 18.5MeV ( at K=12). The PACE4 code slightly gives good agreement with ENDF determined excitation function at some computed radionuclide production considered under this study,while the rest results are unfitted with the ENDF data. It has been observed that complete fusion, incomplete fusion and pre-equilibrium emission processes play important roles in heavy ion reactions at these energies. The observed disagreement may be credited to the contribution from the incomplete fusion reaction, pre-equilibrium emission processes and light particle reaction is not well taken into account by PACE4 statistical model code.en-USEvaluation of ReactionCross-Section for DeuteronInduced Radioisotope125I62ZN15o and 103PDDifferent EnergyRanges UsingPACE 4 CODEThesis
