Molecular electron density from electron scattering

Abstract The small-angle elastic scattering by high-energy electron for hydrocarbons (ethane, ethylene, propane, cyclopropane, allene, pyridine etc.) and other molecules (carbon monoxide, sulfer dioxide and hydrogen sulfide) were calculated by Hartree–Fock self-consistent field wavefunctions using various basis sets and compared with the experimental intensities measured using 30 keV electrons at s =0.5–12 A −1 to check the qualities of their basis sets and to obtain information on the electron densities in molecules.
