给出了快速里德堡原子-中性分子碰撞的总电离 sigma/sub I/ 和总破坏 sigma/sub d/（电离 + 激发 + 去激发）截面的速度依赖性的第一次测量结果。观察到的共振结构以及 sigma/sub I/ 和 sigma/sub d/ 的绝对大小明确证实了与快原子结合的里德伯电子准自由散射的预测。数据还强烈暗示离子核心也有同样的作用。
The results of the first measurements of the velocity dependence of the total ionization sigma/sub I/ and the total destruction sigma/sub d/ (ionization + excitation + deexcitation) cross sections for fast Rydberg-atom-neutral-molecule collisions are presented. The observed resonant structure in and the absolute magnitudes of sigma/sub I/ and sigma/sub d/ unambiguously confirm the prediction that the Rydberg electron bound to a fast atom scatters quasifreely. The data also strongly hint that the ionic core does the same.
