Abstract(summary):

Excitation functions were measured by stacked-foil technique for the Zn-nat(p,x)Cu-61, Zn-66(p,x)Cu-61, Zn-68(p,x)Cu-61 and Zn-nat(p,x)Cu-60 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 Zn-64(p,x)Cu-61 process were also deduced. Integral thick target yields were calculated for the Zn-64(p,x)Cu-61 and Zn-nat,Zn-64(p,x)Cu-60 processes and irradiation parameters were elaborated for the Cu-61 production via the Zn-64+p reactions for low and middle energy accelerators. According to our calculations the yield of Cu-61 amounts to 1.02(.)10(11) Bq(.)A(-1.)s(-1) (9.9 mCi(.)muA(-1.)h(-1)) from 19-->10 MeV while it reaches 3.91(.)10(11) Bq(.)A(-1.)s(-1) (38 mCi(.)muA(-1.)h(-1)) in the energy range of 67-->60 MeV.
