在13.5 ~ 14.8 MeV的中子能量范围内，对75As (n, 2n) 74As、75As (n, p) 75m+ gGe、75As (n, α) 72m+ gGa反应进行了与27Al (n, α) 24Na反应相关的中子嬗变掺杂研究。测量采用同轴HPGe探测器进行γ探测。以纯度为99.9%的天然雄黄（As2S2）粉为样品。快中子是由T (d, n) 4He反应产生的。所得结果与已有数据进行了比较
Cross sections which is relevant in research of neutron transmutation doping of some important semiconducting materials were measured at neutron energies from 13.5 to 14.8 MeV for the reactions 75As (n, 2n) 74As, 75As (n, p) 75m+ gGe, 75As (n, α) 72m+ gGa by activation relative to the 27Al (n, α) 24Na reaction. Measurements were carried out by γ-detection using a coaxial HPGe detector. Natural realgar (As2S2) powder of 99.9% purity was used as samples. Fast neutrons were produced by the T (d, n) 4He reaction. The results obtained are compared with existing data
