氢的负离子在原子物理学和天体物理学中仍然很重要。两个电子之间的相关性在基态已经很强了，这是这个三体系统中唯一的束缚态。这种状态吸引了早期的兴趣，特别是在描述恒星大气层的阿布拉塞卡和其他人。最近，双激发态的丰富光谱，以及高于14.35 eV的分裂能量的双逃逸的性质，已经成为我们理解量子物理中高度相关的不可分离问题的核心。这篇文章是对H−的故事的一个调查，因为它在过去的70年里发展了。
The negative ion of hydrogen continues to be important in atomic physics and astrophysics. Correlations between the two electrons are strong already in the ground state, the only bound state in this three-body system. This state attracted early interest, especially for the description of stellar atmospheres by Chandrasekhar and others. More recently, the rich spectrum of doubly-excited states, and the nature of the double escape above the break-up energy of 14.35 eV, have been central to our understanding of highly-correlated, non-separable problems in quantum physics. This article is a survey of the story of H−as it has developed over the last seventy years.
