Abstract
The possibility of photonuclear production of 111In radioisotope has been
investigated. The enriched target 112Sn was irradiated at the linear electron accelerator
LUE-75 of A. Alikhanian National Science Laboratory (Yerevan, Armenia) at the bremsstrahlung
endpoint energy Eγmax = 55 MeV. The cross section per equivalent quantum for
reactions 112Sn(γ,x)111In, 112Sn(γ,n)111Sn,
112Sn(γ,2n)110Sn, 112Sn(γ,3n)109Sn,112
Sn(γ,pn)110mIn, 112Sn(γ,pn)110g110In,
112Sn(γ,p2n)109In have been measured via the method of activation and off-line
γ-ray spectrometric technique. The cross section per equivalent quantum of the 111In
in photonuclear reaction was compared with its cross section in proton induced reaction on cadmium
targets and other possible 111In production routes. It is shown that the photonuclear method
can be used for the production of 111In.
