Excitation functions and yields for 111In production using 113,114,natCd(p,xn)111In reactions with 65 MeV protons

Excitation functions for the 113Cd(p,3n)111In and 114Cd(p,4n)111In reactions were measured by the stacked-foil technique in the energy range from 63 to 3 MeV. The results were compared with theoretical calculations based on the hybrid model using the well developed computer code ALICE. For the same energy range, the effective cross-sections were determined for the natCd(p,xn)111In reactions. At the initial proton energy of 63 MeV for production of 111In from 113Cd, 114Cd and natCd the cumulative yields were found as 16.7, 15.7 and 10.4 mCi/μAh respectively. The contamination of the undesired nuclide 114mIn was determined. The no carrier added (NCA) 111In was separated from the cadmium cyclotron-target by a procedure based on ion exchange chemistry. The radionuclide purity of the final radioindium was determined. (author)
