Abstract

The production possibility of the medically relevant radioisotope 161Tb using a 9Be + p (Ep = 18 MeV) neutron source was investigated at the MGC cyclotron of ATOMKI. The 161Tb is formed via the 160Gd(n,γ)161Gd → 161Tb nuclear process. The available EOB yield was about 8000 Bq C−1 g−1. Predictions based on Monte Carlo calculations in conjunction with TENDL-2017 cross-section data overestimate the experimental results. These preliminary results indicate that secondary neutrons generated in a high-intensity medical radioisotope production target station could be useful for research-scale 161Tb production.
