Preliminary results of the theranostic ⁴⁷Sc cyclotron proton-induced production with enriched ⁴⁸Ti, ⁴⁹Ti and ⁵⁰Ti targets

The scientific community interest in the production of the theranostic 47Sc is due to its medical favourable decay characteristics suitable for both SPECT imaging and therapeutic purposes. Considering the SPES cyclotron, this work is focused on the measurement of the 48/49/50Ti(p,x)47Sc and 46Sc cross sections up to 70 MeV. In fact, 46Sc is the main co-produced contaminant, since it has a longer half-life than the theranostic 47Sc. Enriched 48/49/50Ti powder were deposited on aluminum backing by using the HIVIPP technique and the obtained targets were characterized by Elastic Back Scattering at the INFN-LNL. Experimental data are compared with the scarce literature and the TALYS results, obtained using the default parameters.
