Abstract : The potential between an electron and a static atom is fomulated on the basis of creening-constant-type wave functions, as are characteristic of the Slater orbital atom. Universal functions are constructed so as to characterize any atom with atomic number Z from 1 to 86. The low energy elastic scattering properties of atoms are investigated on the basis of such a potential,AND THE CROSS SECTIONS ARE CALCULATED FOR ALL OF THE ATOMS FROM Z = 1 to 86. The results are compared with those which the writer obtained with the Thomas-Fermi model of the atom. Results are given for the cross sections as a function of energy, in some specific cases. Qualitative agreement between theory and experiment results from such calculations. A polarization potential must be added to static atom potentials in order to obtain quantitative agreement between theory and experiment. (Author)
