Possibilities of production of diagnostic isotope ~(111)In using neutron- and proton-induced reactions on tin isotopes

摘要

We have measured 16 neutron- and 7 proton-induced reactions on tin isotopes using the natural tin as well as the enriched ~(112)Sn targets (to 62.5percent and 84percent) by activation method and obtained the cross sections on individual isotopes therefrom. These reactions are important for proper establishing of possible ways of production of diagnostic isotope ~(111)In with very high purity via radioisotope generators. The measurements have been performed at the neutron energy of 14.6 MeV and the proton energy of 23.6 MeV. The experimental data have been compared to the cross section calculations with account for the pre-equilibrium emission, and the feasibility of possible production of ~(111)In has been deduced.
