Abstract

Production cross sections of medical radionuclides ¹¹¹In, ^110mIn and ¹⁰⁹Cd were investigated in the α-particle-induced reactions on natural silver up to 50 MeV. The stacked-foil activation technique and γ-ray spectrometry were used to determine the cross sections. The excitation functions of byproducts ^{104g,105,106m,110m}Ag, ^107,111mCd and ^{107g,108g,108m,109,110g}In were also determined. Physical yields of ¹¹¹In, ^110mIn and ¹⁰⁹Cd were deduced based on the measured cross sections.
