ABSTRACT
Cross-sections of proton induced nuclear reactions on natural thallium have been studied for investigation of the production of the medical important (201)Tl diagnostic radioisotope. The excitation functions of (204m)Pb, (203)Pb, (202m)Pb, (201)Pb, (200)Pb, (199)Pb, (202)Tl (direct, cumulative), (201)Tl (direct, cumulative), (200)Tl(direct), and (203)Hg were measured up to 42MeV proton energy by stacked foil technique and activation method. The experimental data were compared with the critically analyzed experimental data in the literature, with the IAEA recommended data and with the results of model calculations by using the ALICE-IPPE, EMPIRE-II and TALYS codes.

The excitation function of the proton exchange reactions on gold was investigated in the energy range from threshold up to 20MeV. We presented our experimental results upto 14MeV stacked-foil technique was used, the target was of high purity gold foils (99.99%.) Reactions cross-sections and excitation functions were studied. Both isomeric level cross sections of (197)Hg were measured and calculated theoretically using the DDHMS routine of the EMPIRE-II (v2.19) code. Isomeric cross-section ratios for the pair (197m,g)Hg were calculated and presented as a function of proton energy.
