We present new experimental electron energy loss distribution functions for ethylene (C2H4) measured with two different apparatus (Liege and Madrid) in different incident electron energy ranges. Theoretical cross sections for electron scattering from C2H4 were calculated using the screening-corrected additivity rule (LAM-SCAR) method. Through a critical comparison of our new data and existing results from other groups, we obtain a self-consistent set of recommended interaction cross section values and energy loss spectra. Finally, electron tracks in C2H4 are simulated with our Low Energy Particle Track Simulation (LEPTS) in order to demonstrate the efficacy of our recommended data. (c) 2013 Elsevier B.V.
