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

Excitation curves for reactions induced by proton beams up to 36 MeV on highly enriched 116Cd 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,116m1In and 115Cd. 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 116Cd(p,3n) reaction for production of 114mIn is confirmed.
