Investigation of activation cross sections of proton induced reactions on indium up to 70 MeV for practical applications

• Proton induced reactions on natural indium up to 70 MeV.
• Stacked foil irradiation including monitor and energy degrader foils.
• Comparison of experimental results with the TENDL-2014 library.
• Discussion of medical and industrial applications.

Excitation functions were measured for production of the 113,111,110Sn, 115m,114m,113m,112m,111g,110gIn and 111m,109Cd radioisotopes by bombardment of In targets with proton beams up to 70 MeV, some of them for the first time. The new results are compared with the earlier experimental data and with the theoretical data in the TENDL-2014 (Talys1.6 based) library. Thick target yields were deduced and application of the new data for production of medically relevant 110mIn,111gIn,113mIn and 114mIn, as well as applicability for thin layer activation (TLA) are discussed.
