| 内容記述 | We measured the yields of radionuclides after neutron irradiation on an enriched 68ZnO sample covered with polyethylene blocks. The neutrons were generated from the 9Be(d,n) reaction by 40 and 50 MeV deuterons. For 50 MeV deuterons we found anomalously large yields of 67Ga, 66Ga, 69mZn, and 64Cu, more than 20-times larger than the yields for a 68ZnO sample without the polyethylene blocks. At the same time, the yields of the same radioisotopes from an enriched metallic 68Zn sample were almost insensitive to the presence of polyethylene. On the other hand, for 40 MeV deuterons the enhanced production was not observed. This finding would provide a unique capability of accelerator neutrons to simultaneously produce large amounts of several radioisotopes via the neutrons- as well as protons-induced reactions on a single sample. The experimental data were compared with the yields calculated by the simulation code Particle and Heavy Ion Transport code System (PHITS). The calculated yields of these radioisotopes produced from the 68ZnO sample covered with the polyethylene blocks considerably disagree with the measured ones, while for the 68ZnO sample without the blocks they agree with each other. | |||||
