Abstract 47 Sc 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 at 47 Sc production using enriched 48 Ti, 49 Ti and 50 Ti targets from 23 up to 70 MeV. Since the co-production of contaminant isotopes is a key issue, and 46 Sc is the main one having a longer half-life than 47 Sc, the 48/49/50 Ti(p,x) 47 Sc and 46 Sc cross sections are presented and compared with the scarce literature data and TALYS estimations.
