title: Excitation function of the 192Os(3He,4n)-reaction for production of 191Pt.
abstract: In search of an alternative production route of the therapeutically and environmentally interesting radionuclide (191)Pt (T(1/2)=2.8 d), excitation function of the (192)Os((3)He,4n)(191)Pt reaction was measured from its threshold up to 36 MeV. Thin samples of enriched (192)Os were prepared by electrodeposition on Ni-foils, and the conventional stacked-foil technique was used for cross-section measurements. The experimental data were compared with the results of theoretical calculations using the codes ALICE-IPPE and TALYS. Good agreement was found with TALYS. The theoretical thick target yield of (191)Pt over the energy range E(3He)=36-->25 MeV amounts to 6.7 MBq/microA h. A comparison of various investigated production methods of (191)Pt is given. The here investigated (192)Os((3)He,4n)-process leads to very high-purity (191)Pt (>99.5%).
