For the first time, cross sections of the ¹⁵¹Eu(α,xn)^155−xTb (x = 2–6) reactions were measured by stack foil technique in the alpha particle range 60 → 19 MeV. Experimental excitation functions were compared with theoretical data from TENDL 2019 library and calculated by EMPIRE-3.2.3 code. Thick target yields for terbium radioisotopes were calculated. The possibility of the practical application of the studied reactions for the production of ¹⁵²Tb and ¹⁴⁹Tb was assessed. It was shown that higher energy of alpha particles is required to produce ¹⁴⁹Tb. The production of ¹⁵²Tb is affected by the influence of side reactions. It is possible to decrease the total content of impurities (¹⁵³Tb+¹⁵¹Tb) at EOB to 18% of the activity of the ¹⁵²Tb under 8-hour irradiation by limiting the energy range of incident particles to 42 → 34 MeV. The ¹⁵²Tb yield will be 222 MBq/μA.

第一次，通过堆叠箔技术在60→19 MeV的α粒子范围内测量了¹⁵¹ Eu（α，x n）^{155- x} Tb（x = 2–6）反应的截面。将实验激励函数与TENDL 2019库中的理论数据进行比较，并通过EMPIRE-3.2.3代码进行计算。计算了radio放射性同位素的目标浓收率。评估了所研究的反应在生产¹⁵² Tb和¹⁴⁹ Tb中的实际应用的可能性。结果表明，生产¹⁴⁹ Tb需要更高的α粒子能量。¹⁵²的生产Tb受副反应的影响。通过将入射粒子的能量范围限制为42→34 MeV，可以在8小时的照射下将EOB处的杂质总含量（¹⁵³ Tb + ¹⁵¹ Tb）降至¹⁵² Tb活性的18％。在¹⁵² Tb的产量将是222活度/μA。
