The cross sections for nuclear reactions Er(α,x) were measured in the energy range 60 → 10 MeV using the stacked-foil technique. The experiments were carried out in a wider energy range in comparison with previous works. The results are consistent with other studies and modeling using TENDL-2019. The Tm yield was 5.4 MBq/μAh in the range 60 → 30 MeV, and the main long-lived impurity is Tm (0.78% in terms of activity). The Tm yield is 4.6 MBq/μAh (60 → 40 MeV). Yb is formed with a yield of 1.0 MBq/μAh in the energy range 60 → 20 MeV.
采用堆积箔技术测量了 Er(α,x)核反应的横截面积，能量范围为 60 MeV 至 10 MeV。与以前的工作相比，实验在更宽的能量范围内进行。结果与其他研究和使用 TENDL-2019 的建模一致。在 60 MeV 至 30 MeV 的范围内，Tm 的产额为 5.4 MBq/μAh，主要的长寿命杂质是 Tm（以活度计为 0.78%）。在 60 MeV 至 40 MeV 的范围内，Tm 的产额为 4.6 MBq/μAh。在 60 MeV 至 20 MeV 的能量范围内，Yb 的产额为 1.0 MBq/μAh。
