摘要

利用叠片活化技术结合高分辨率γ射线能谱法，在8-17.5 MeV能量范围内测量了天然钬(natHo(d,x)165Er和natHo(d,x)166g，mHo上氘核诱导的核反应截面。总体而言，与先前的测量结果吻合良好，而TENDL-2021和TENDL-2023的理论预测仅与实验数据部分一致。亚稳同位素杂质166mHo的贡献估计可以忽略不计。

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.
