Abstract
43Sc and 44Sc are positron emitter radionuclides that, in conjunction with the β− emitter 47Sc, represent one of the most promising possibilities for theranostics in nuclear medicine. Their availability in suitable quantity and quality for medical applications is an open issue and their production with medical cyclotrons represents a scientific and technological challenge. For this purpose, an accurate knowledge of the production cross sections is mandatory. In this paper, we report on the cross section measurement of the reactions 43Ca(p,n)43Sc, 44Ca(p,2n) 43Sc, 46Ti(p,α)43Sc, and 44Ca(p,n)44Sc at the Bern University Hospital cyclotron. A study of the production yield and purity performed by using commercially available enriched target materials is also presented.
