检验了多维γ能谱仪中子活化分析方法的可行性。日本地质调查局 (GSJ) 发布的参考火成岩（JP-1、JB-1a 和 JB-1）样本和阿连德陨石参考样本在研究反应堆中受到辐照，并使用 12 个带有 BGO 康普顿抑制器（称为 GEMINI）的锗探测器阵列测量通过中子俘获反应产生的放射性同位素产生的多种 γ 射线。同时观察到三十种元素，没有发生化学分离。观察到的最小成分是JP-1中含有的Eu，丰度为4ppb。
Feasibility of the method of multidimensional γ-ray spectrometer for neutron activation analysis was examined. Reference igneous rock (JP-1, JB-1a and JB-1) samples issued by the Geological Survey of Japan (GSJ) and the Allende meteorite reference sample were irradiated in a research reactor, and multiple γ-rays from the produced radioisotopes via neutron capture reactions were measured using an array of twelve germanium detectors with BGO Compton suppressors called GEMINI. Simultaneously thirty elements were observed with no chemical separation. The observed smallest component was Eu contained in JP-1 with abundance of 4 ppb.
