摘要

利用叠片技术测量了153Eu(α,x)151 ~ 156tb，153Gd在α粒子能量60.0 ~ 19.8 MeV范围内的反应截面。所有数据均为首次获得。实验数据与TENDL-2023数据库中的理论值进行了比较。计算了活化产物厚靶收率。对153Eu(α,2n)155Tb和153Eu(α,5n) 152g Tb反应进行了比较。在30.2 ~ 27.5 MeV的能量范围内，该反应可产生2.17 MBq/（μA·h）的155Tb，最小156Tb含量为2.1%。

Alpha particle induced reactions on 153Eu as possible routes for 152Tb and 155Tb production

Cross-sections for the ¹⁵³Eu(α,x)^151-156Tb,¹⁵³Gd reactions were measured by using the stacked foil technique within alpha-particle energy range of 60.0 to 19.8 MeV. All of the data were obtained for the first time. Experimental data were compared with theoretical values from the TENDL-2023 database. Thick target yields of activation products were calculated. The reactions ¹⁵³Eu(α,2n)¹⁵⁵Tb and ¹⁵³Eu(α,5n) ^152g Tb were compared with other ¹⁵⁵Tb and ¹⁵²Tb production routes. The reaction allows producing up to 2.17 MBq/(μA·h) of ¹⁵⁵Tb with the minimum possible ¹⁵⁶Tb content of 2.1 % within the energy range of 30.2 to 27.5 MeV.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
