在室温下，用硅收集器探针测量了铍、碳和钨共沉积的高能氘的俘获。用热脱附谱测定了高温下捕获的氢的释放情况。在室温下，氢与碳和BeO共沉积，分别为0.41个D原子/C原子和0.38个D原子/BeO。没有观察到氢与钨的共沉积。BeO共沉积的氢从400K开始热释放，所有的氢在800K以上释放。
The trapping of energetic deuterium codeposited with beryllium, carbon and tungsten has been measured on a silicon collector probe at room temperature. The subsequent release of the trapped deuterium at elevated temperatures was determined by thermal desorption spectroscopy. At room temperature, deuterium codeposits both with carbon and BeO with a ration of 0.41 D-atorns/C-atom and 0.38 D-atoms/BeO, respectively. No codeposition of deuterium with tungsten is observed. The thermal release of codeposited hydrogen from BeO begins at 400 K. All hydrogen is released at temperatures above 800 K.
