RESUMO
Dark field electronmicrographs of atoms of palladium, iodine, platinum, osmium, and uranium in model compounds have been obtained. Statistical analyses and a series of blind tests demonstrate the validity of the results. Moreover, optical density measurements of the images indicate that the observed relative scattering cross-sections of these atoms agree well with the theoretical cross-sections calculated from a Thomas-Fermi-Dirac model of the atom.
