Excitation functions of ^66,67Ga and ⁶⁵Zn, generally used for beam intensity monitoring and/or beam energy determination; ⁵⁷Co and ⁵⁸Co produced by ^natCu(α,x) reactions were measured from their respective thresholds up to 50 MeV using standard stacked foil activation technique followed by high resolution gamma ray spectrometric method. Thick target yields were calculated for these radionuclides using the experimentally determined cross sections and stopping power of natural Cu. Experimentally obtained results were compared with the recently published data, IAEA recommended data and TENDL-2019 data based on the TALYS-1.95 code. The present data are found to be in good agreement with the literature data within experimental uncertainties.

^66,67 Ga 和⁶⁵ Zn 的激发函数，通常用于光束强度监测和/或光束能量测定；⁵⁷ Co和⁵⁸联合产生的通过^NAT的Cu（α,x) 反应使用标准堆叠箔激活技术从它们各自的阈值测量到 50 MeV，然后使用高分辨率伽马射线光谱法。使用实验确定的横截面和天然铜的阻止能力计算了这些放射性核素的厚靶产额。将实验获得的结果与最近公布的数据、IAEA 推荐的数据和基于 TALYS-1.95 代码的 TENDL-2019 数据进行了比较。发现目前的数据在实验不确定性范围内与文献数据非常吻合。
