We report the first direct measurement of the kinetic energy of exoelectrons produced by collisions of vibrationally excited molecules with a low work function metal surface exhibiting electron excitations of 64% (most probable) and 95% (maximum) of the initial vibrational energy. This remarkable efficiency for vibrational-to-electronic energy transfer is in good agreement with previous results suggesting the coupling of multiple vibrational quanta to a single electron.
我们报告了首例通过碰撞振动激发分子与具有 64%（最可能）和 95%（最大）初始振动能量电子激发的低功函数金属表面产生的外电子动能的直接测量。这种振动到电子能量转移的显著效率与先前的结果一致，表明多个振动量子与单个电子的耦合。
