Abstract：
Evaluation of the 63Cu(α,n)66Ga, 65Cu(α,2n) 67Ga and 65Cu(α,n)68Ga reactions was done to study the production of medical radionuclides 66Ga, 67Ga and 68Ga respectively. 63Cu(α,2n)65Ga and 65Cu(α,3n)66Ga reactions were also evaluated for the estimation of radioisotopic impurities. Cross section data of each reaction were compiled and normalized to the standard values of decay data and monitor reaction. To check the consistency of the literature data, three nuclear model calculations were performed, using nuclear model codes; TAYLS 1.9, ALICE-IPPE, and EMPIRE 3.2. A well-developed evaluation methodology based on the normalized experimental data and nuclear model calculations was used to generate the statistically fitted cross sections. From the fitted cross sections, thick target yields for each reaction were calculated for the estimation of radioisotopic impurities. Finally, a suitable energy region for the production of 66Ga, 67Ga and 68Ga was suggested with a minimum level of radioisotopic impurities.
摘要：
63Cu(α，n)66Ga,65Cu(α，2n)67Ga和65Cu(α，n）进行68Ga反应以研究医用放射性核素66Ga的产生，67Ga和68Ga分别。63Cu(α,2n)65Ga和65Cu(α，还评估了3n)66Ga反应以估计放射性同位素杂质。将每个反应的横截面数据汇编并归一化为衰变数据的标准值并监测反应。为了检查文献数据的一致性，进行了三次核模型计算，使用核模型代码；TAYLS1.9，ALICE-IPPE，和帝国3.2。使用基于归一化实验数据和核模型计算的完善的评估方法来生成统计拟合的横截面。从装配的横截面看,计算每个反应的厚目标产率，以估算放射性同位素杂质。最后,生产66Ga的合适能量区，67Ga和68Ga被建议具有最低水平的放射性同位素杂质。
