Soft electron impact ionization in crossed molecular beam reactive scattering: The dynamics of the O(~3P) + C_2H_2 reaction

摘要

Soft ionization by low-energy, tunable electrons is implemented for the first time in crossed molecular beam reactive scattering experiments with mass-spectrometric detection. The power of the method, which permits the suppression of the dissociative ionization of interfering species, is exemplified with the study of the O(~3P) + C_2H_2 multichannel reaction.
