Production of the therapeutic radioisotope 114mIn through the 116Cd(p,3n)114mIn reaction

Abstract Excitation curves for reactions induced by proton beams up to 36 MeV on highly enriched 116 Cd targets were assessed. The standard stacked foil method, with monitoring of beam parameters over the whole energy region, and high resolution gamma spectrometry were used. We report cross sections for reactions leading to 113m ,114m,115m,116m1 In and 115 Cd. A comparison with some earlier experimental data and with results of theoretical model codes ALICE-IPPE and EMPIRE are presented. Our previous estimation of use of the 116 Cd(p,3n) reaction for production of 114m In is confirmed.
