用冷靶反冲离子动量谱测量了85~400 eV光子对He的双电离与单电离之比。这项技术允许消除到目前为止关于这一主题的文献中讨论的所有可能的系统误差。我们发现在这个能量范围内的比率比先前假设的要低约25%。{版权所有}{1996年美国物理学会。}
The ratio of double to single ionization of He by 85{endash}400 eV photons has been measured using cold target recoil ion momentum spectroscopy. This technique allows the elimination of all possible systematic errors discussed so far in the literature on this subject. We find the ratio in this energy range to be about 25{percent} lower than previously assumed. {copyright} {ital 1996 The American Physical Society.}
