Abstract : A summary is given on research in which electron diffraction was employed to measure experimentally the shape of charge distributions surrounding atoms and molecules. The research showed that: It was possible to obtain experimental intensity data of sufficient accuracy to provide sensitive tests for the best available theoretical wave functions for simple atomic systems. That the Born theory of scattering is amazingly accurate. (.1% or better) for atoms (Ne) at high incident electron energies (40keV); and that data for simple polyatomic systems (N2, CO2, N2O, CH4) can be obtained which provides a more sensitive measure of deviations of the electron density from a test model of the density than any currently available theoretical wave function.
