Abstract : Mass spectra of ethylenes (C2H4 and CH2CD2) were obtained after charge exchange with slow positive ions. The intensities of the peaks were plotted as a function of the energy absorbed by the molecule during the charge exchange. The structure and dissociation of ethylene are discussed. Three distinct processes for the formation of the acetylene ion are proposed. Integration of the breakdown graph gives a mass spectrum in reasonable agreement with that obtained in electron impact.
