Electron scattering from alkenes in the energy range 200–4500 eV

Total electron scattering cross sections (TCS) of C2H4 (ethylene), C3H6 (propene), C4H8 (butene) and C4H6 (1,3-butadiene) have been obtained for 200–4500 eV electrons by the measurement of electron-beam intensity attenuation through a gas cell. An analytical expression is deduced to predict the intermediate energy TCS of chain-like hydrocarbons with C–C single and double bonds. The present experimental TCS are compared with the previous experimental measurements and the predictions by theoretical models.
