我们研究了130 - 240 eV圆偏振光子对H-2的单光子双电离。我们发现一个双缝干涉图案的总和动量的两个电子在分子框架中生存的集成超过所有其他自由度。差动量和单个电子动量分布并没有显示出这样一个强大的干涉图案。我们表明，这种干扰的结果从一个非Heitler-伦敦分数的H-2基态的两个电子是在同一个原子中心。
We investigate single-photon double ionization of H-2 by 130 to 240 eV circularly polarized photons. We find a double slitlike interference pattern in the sum momentum of both electrons in the molecular frame which survives integration over all other degrees of freedom. The difference momentum and the individual electron momentum distributions do not show such a robust interference pattern. We show that this interference results from a non-Heitler-London fraction of the H-2 ground state where both electrons are at the same atomic center.
