Momentum imaging experiments on dissociative electron attachment (DEA) to a water molecule are combined with ab initio theoretical calculations of the angular dependence of the quantum mechanical amplitude for electron attachment to provide a detailed picture of the molecular dynamics of dissociation attachment via the two lowest energy Feshbach resonances. The combination of momentum imaging experiments and theory can reveal dissociation dynamics for which the axial recoil approximation breaks down and thus provides a powerful reaction microscope for DEA to polyatomics.
对水分子的离解电子俘获（DEA）进行动量成像实验，并结合从头计算理论对电子俘获的量子力学振幅的角依赖性进行计算，为通过两个最低能量 Feshbach 共振的分子动力学提供了详细的描述。动量成像实验和理论的结合可以揭示轴向反冲近似失效的离解动力学，因此为多原子的 DEA 提供了一种强大的反应显微镜。
