Abstract

The radionuclide 161Tb (T1/2=6.89 d) is potentially important for internal radiotherapy. It is generally produced through the 160Gd(n,γ) 161Gd → 161Tb route at research reactors. In this work the possibility of its production at a cyclotron was investigated. Determination of the excitation function of the 160Gd(d,x)161Tb production route and that of the disturbing 160Gd(d,2n)- 160Tb side reaction was done over the deuteron energy range up to 50 MeV using the stacked-foil technique and high-resolution γ-ray spectrometry. A comparison of this production route with the established (n,γ) reaction at a nuclear reactor is made.
