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

Gaia Pupillo,

Abstract: 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 at 47Sc production using enriched 48Ti, 49Ti and 50Ti targets from 23 up to 70 MeV. Since the co-production of contaminant isotopes is a key issue, and 46Sc is the main one having a longer half-life than 47Sc, the 48/49/50Ti(p,x)47Sc and 46Sc cross sect… Show more

Excitation functions of the $$^{86}$$ 86 Sr(d,n)$$^{87m,87g}$$ 87 m , 87 g Y, $$^{86}$$ 86 Sr(d,2n)$$^{86m,86g}$$ 86 m , 86 g Y and $$^{86}$$ 86 Sr(d,3n)$$^{85m,85g}$$ 85 m , 85 g Y reactions on enriched $$^{86}$$ 86 Sr target were measured by the activation technique up to deuteron energies of 49 MeV. The isomeric cross-section ratios as a function of projectile energy were deduced from the measured data for $$^{87m}$$ 87 m Y, $$^{87g}$$ 87 g Y(cum), $$^{86m}$$ 86 m Y, $$^{86g}$$ 86 g Y(cum), $$^{85m}$$ 85 m Y and $$^{85g}$$ 85 g Y pairs for the same energy range. All measurements are reported for the first time. The experimental data were compared with the data from the TENDL library which is based on TALYS calculation with default parameters. No satisfactory agreement was observed. Nuclear model calculations were then performed using the codes TALYS and EMPIRE with some parameter adjustments, and compared with the experimental data. The quality of the agreement between experimental data and model calculations was numerically quantified. In general, the data as well as the isomeric cross-section ratios are partially reproduced by the model calculations, provided the input model parameters are properly chosen and the level structure of the product nucleus is thoughtfully considered.
