Proton-induced reactions for 47Sc (and 46Sc) production: new nuclear cross section measurements on enriched titanium targets

Abstract47Sc is a theranostic radionuclide under the spotlight of the scientific community thanks to its potential for SPECT imaging and therapeutic applications. This work presents the recent measurements of proton-induced nuclear reaction cross-sections aimed at47Sc production using enriched48Ti,49Ti and50Ti targets from 23 up to 70  MeV. Since the co-production of contaminant isotopes is a key issue, and46Sc is the main one having a longer half-life than47Sc, the48/49/50Ti(p,x)47Sc and46Sc cross sections are presented and compared with the scarce literature data and TALYS estimations.
