利用67Zn(n，p，)67Cu反应制备了铜的最长寿放射性同位素--铜67。在JRR-1反应堆中，快中子注量率为1.5×1012n/cm2/s，辐照时间为5小时，最高可达93.4%。利用金属的氯络合物，用阴离子交换分离法分离了锌靶中形成的铜-67。考察了~(67)Cu的产率和放化杂质。从1毫克锌中可获得17毫微米的67Cu。未发现除64Cu以外的其他放射性杂质。即使使用了浓缩靶，也比67Cu产生了更多的MCU。~(67)Cu在照射后即刻占总铜放射性的26%。
Copper-67, the longest-lived radioisotope of copper, was prepared by using the reaction 67Zn(n p,)67Cu. Zinc enriched in 67Zn up to 93.4% was irradiated in JRR-1 reactor for 5hr with a fast neutron flux of 1.5×1012n/cm2/sec. Copper-67 formed in the zinc target was separated by anion exchange separation using the chloro-complex of the metals. The yield of 67Cu and radiochemical impurity were investigated. Seventeen millimicrocuries of 67Cu was obtained from 1mg of zinc. No radioactive impurities other than 64Cu were not found. Even with the use of enriched target, a more MCu was produced than 67Cu. The proportion of 67Cu to total copper radioactivity was 26% immediately after the irradiation.
