Formation of medical radioisotope 111 In in photonuclear reactions

Abstract The possibility of photonuclear production of 111 In radioisotope has been investigated. The enriched target 112 Sn was irradiated at the linear electron accelerator LUE-75 of A. Alikhanian National Science Laboratory (Yerevan, Armenia) at the bremsstrahlung endpoint energy E γmax = 55 MeV....

Summary:Abstract The possibility of photonuclear production of 111 In radioisotope has been investigated. The enriched target 112 Sn was irradiated at the linear electron accelerator LUE-75 of A. Alikhanian National Science Laboratory (Yerevan, Armenia) at the bremsstrahlung endpoint energy E γmax = 55 MeV. The cross section per equivalent quantum for reactions 112 Sn(γ,x) 111 In, 112 Sn(γ,n) 111 Sn, 112 Sn(γ,2n) 110 Sn, 112 Sn(γ,3n) 109 Sn, 112 Sn(γ,pn) 110m In, 112 Sn(γ,pn) 110g 110In, 112 Sn(γ,p2n) 109 In have been measured via the method of activation and off-line γ-ray spectrometric technique. The cross section per equivalent quantum of the 111 In in photonuclear reaction was compared with its cross section in proton induced reaction on cadmium targets and other possible 111 In production routes. It is shown that the photonuclear method can be used for the production of 111 In.
