利用电子能量损失谱（EELS）研究了锆中氢与氦泡的缔合作用。常规EELS数据产生13.5eV（类似于氢K边缘，13 eV）的信号，其在空间上分布在气泡的外围周围，并且可以与材料中的氢/氘的浓度相关。超高能量分辨率的EELS在148.6 meV（相当于Zr-H键的范围，130-156 meV）处从包含气泡且没有可见气泡的区域产生信号。这些信号被解释的背景下，无论是气泡表面化学吸附或气泡应力场捕获机制。皇冠版权所有（C）2018由Elsevier Ltd代表Acta Materialia Inc.发布。这是开放政府许可下的开放获取文章。
Electron energy-loss spectroscopy (EELS) is used to investigate the association of hydrogen with helium bubbles in zirconium. Conventional EELS data yield a signal at 13.5 eV (similar to the hydrogen K-edge, 13 eV), which is spatially distributed around the peripheries of bubbles and may correlate with the concentration of hydrogen/deuterium in the material. Ultra-high energy resolution EELS yields a signal at 148.6 meV (comparable to a range of Zr-H bonds, 130-156 meV) from a region containing bubbles and no visible hydrides. These signals are interpreted in the context of either bubble surface chemisorption or bubble stress field trapping mechanisms.
