New cross section data and review of production routes of medically used ${}^{110m}$In

Abstract

Evaluation of nuclear data for production routes of ${}^{110m}$In is in progress in the frame of an IAEA Coordinated Research Project (CRP). New experimental cross section data for the indirect ${}^{nat}$In(p,x)${}^{110}$Sn $⟶$ ${}^{110m}$In and for the direct ${}^{107}$Ag($\alpha$,n)${}^{110m}$In and ${}^{109}$Ag(${}^3$He,2n)${}^{110m}$In production routes and for the satellite impurity reactions ${}^{107}$Ag($\alpha$,xn)${}^{110g,109}$In and ${}^{109}$Ag(${}^3$He,xn)${}^{110g,111,109}$In have been measured by using the activation method, stacked foil irradiation technique and gamma-ray spectrometry. Additional data are reported for production of the ${}^{111}$In diagnostic gamma-emitter via the ${}^{109}$Ag($\alpha$,2n)${}^{111}$In reaction. The earlier experimental data were critically reviewed in order to prepare recommended data and optimal production parameters for the different routes.
