内容記述 |
We predict the production yield of a medical radioisotope 67Cu using 67Zn(n, p)67Cu and 68Zn(n, pn)67Cu reactions with fast neutrons provided from laser-driven neutron sources (LNDSs). The neutrons were generated by the p+9Be and d+9Be reactions with high energy ions accelerated by laser-plasma interaction. We evaluated the yield to be (3.3x0.5)x10^5 atoms for 67Cu, corresponding to a radioactivity of 1.0+-0.2 Bq, for a Zn foil sample with a single laser shot. Using a simulation with this result, we estimated 67Cu production with a high-frequency laser. The result suggests that it is possible to generate 67Cu with a radioactivity of 270 MBq using a future laser system with a frequency of 10 Hz and 10000-s radiation in a hospital. |
