Frustrated charge transfer in vibrationally inelastic Ar⁺+N₂ collisions via hard collision glory scattering.

ABSTRACT: Vibrational energy transfer in collisions between ions and neutrals is a fundamental process in interstellar media, planetary atmospheres, and plasmas. The conventional wisdom is that glancing collisions with large impact parameters are forward-scattered with low vibrational excitation, while hard collisions with small impact parameters are sideway- or backward-scattered with relatively high vibrational excitation. Here, we report experimental observations with a three-dimensional velocity-map imaging crossed-beam apparatus in the inelastic scattering process Ar⁺+N₂(v'' = 0, J'')→Ar⁺+N₂(v', J'), where all the vibrationally excited N₂ products are dominated by forward scattering, contradicting the textbook model.
