| 内容記述 | Excitation functions were measured by the stacked-foil technique for 59Co(alpha,n) 62Cu, 59Co(alpha,2n)61Cu and 59Co(alpha,3n)60Cu nuclear reactions up to 60 MeV. The excitation functions were compared with the published data. The optimum energy range for the production of 61Cu and 62Cu was found to be 39-> 18 and 18.5-> 6 MeV, respectively. The calculated thick target yield of 61Cu in this energy range was 21.0 mCi/muA(supposing one half-life activation time); and 16.2 mCi/muA (supposing three half-life activation time) for 62Cu. The level of 60Cu and 62Cu impurities at 61Cu production decreases to around 1% after a 1 h cooling time. The practical yield in this case is 17.2 mCi/muA. For production of 62Cu the contamination level of 61Cu increases continuously after EOB, but remains below 1% if the cooling time is less than 0.5 h(1.9mCi/muA at 0.5 h after EOB). Unfortunately, in the case of 60Cu production, the contamination level of 61Cu and 62Cu at EOB was found to be 18.4% and 47.9%, respectively, of the produced 60Cu activity (6.4 mCi/muA, after 60 min irradiation time, in the energy interval 60-> 44 MeV). |
