Abstract:Dissociative electron transfer in collisions between neutral potassium atoms and neutral ethanol molecules yields mainly OH−, followed by C2H5O−, O−, CH3− and CH2−.The dynamics of negative ions have been investigated by recording time‐of‐flight mass spectra in a wide range of collision energies from 17.5 to 350 eV in the lab frame, where the branching ratios show a relevant energy dependence for low/intermediate collision energies.The dominant fragmentation channel in the whole energy range investigated has be… Show more
