Cross‐sections have been measured for the charge neutrilization if ions from benzene in kiloelectron‐volt collisions with benezene target molecules. Measured values range from 65 Å 2 for the symmetric [C 6 H 6 ] + C 6 H 6 resonant reactions to 8 Å 2 for [C 3 H 3 ] + C 6 H 6 reactions. Cross‐sections computed using a simple resonance charge transfer model compare favourably with experimental data for the symmetric reactions. The cross‐sections for asymmetric reactions are smaller that those for they symmetric system and magnitudes of the asymmetric cross‐sections are correlated with recombination energies of the respective ions.
