Measurement of the excitation function of 96Zr(α,n)99Mo for an alternative production source of medical radioisotopes

Abstract

To assess the feasibility of an innovative medical 99Mo/99mTc production route using a low-energy accelerator, we measured the excitation function of the 96Zr(α,n)99Mo reaction in the energy range from 11 to 23 MeV using a 24 MeV α beam. The present results showed higher values than past data in the peak region, although both data were almost identical above 17 MeV. The production rate of 99Mo from a 96Zr target with incident energies of α particles below 23 MeV was also estimated using the measured excitation function.
