Abstract
The availability of the theranostic radionuclide 47Sc is hindered by the lack of a reliable high purity production method. The aim of this work is to evaluate a less considered pathway exploiting deuteron beams on enriched 49Ti targets. The investigation started from the measurements of the production cross sections of the emergent radionuclide 47Sc, as well as of the co-produced contaminants which play an important role on the final purity and in the evaluation of the dose eventually administered to a patient. Enriched 49Ti targets, manufactured at the INFN-LNL (National Institute of Nuclear Physics-Legnaro National Laboratories), were activated in several irradiation runs carried out at the GIP ARRONAX (Group of Public Interest Accelerator for Research in Radiochemistry and Oncology in Nantes-Atlantique) facility cyclotron utilizing the tunable 15÷35 MeV deuteron beam. The obtained cross section trends, which constitute the first measurement for some radionuclides, are compared to theoretical curves and literature data, when available. The experimental cross sections are then discussed to assess 49Ti(d,x) as a possible production route for 47Sc. The results demonstrated that 49Ti(d,α)47Sc can be considered as a valid alternative production route for the supply of this medically interesting radionuclide.
