Production possibility of <Superscript>61</Superscript>Cu using proton induced nuclear reactions on zinc for PET studies

Summary

Excitation functions were measured by stacked-foil technique for the ^natZn(p,x)⁶¹Cu, ⁶⁶Zn(p,x)⁶¹Cu, ⁶⁸Zn(p,x)⁶¹Cu and ^natZn(p,x)⁶⁰Cu nuclear processes up to 100 MeV. The experimental cross sections were compared with published data. On the base of these excitation functions, the cross sections of ⁶⁴Zn(p,x)⁶¹Cu process were also deduced. Integral thick target yields were calculated for the ⁶⁴Zn(p,x)⁶¹Cu and ^nat,64Zn(p,x)⁶⁰Cu processes and irradiation parameters were elaborated for the ⁶¹Cu production via the ⁶⁴Zn+p reactions for low and middle energy accelerators. According to our calculations the yield of ⁶¹Cu amounts to 1.02 ^. 10¹¹ Bq ^. A^{-1 .} s^-1 (9.9 mCi ^.µ A^{-1 .} h^-1) from 19®10 MeV while it reaches 3.91 ^. 10¹¹ Bq ^. A^{-1 .} s^-1 (38 mCi ^{. µ} A^{-1 .} h^-1) in the energy range of 67®60 MeV.
