  The production of 47Sc, a promising radioisotope for targeted radionuclide
therapy, by means of hospital-cyclotron reactions is investigated. Two possible
routes are considered: the proton-induced reaction on enriched 50Ti targets and
the deuteron-induced reaction on enriched 49Ti targets. The cross-sections of
the reactions are calculated using the TALYS code with optimized parameters and
compared with the available experimental data. The optimal energy ranges for
the production of 47Sc are determined by taking into account the thick-target
yields and the purity of the product. The results show that both reactions can
provide high yields and high purity of 47Sc. The feasibility of producing 47Sc
with a hospital cyclotron is demonstrated by performing realistic simulations
of the irradiation for both 50Ti(p,{\alpha}) and 49Ti(d,{\alpha}) reactions.
