A detailed study was made of the elastic scattering properties of the Thomas-Fermi atom for low-energy electrons. The scattering lengths were determined for all atoms in the periodic table within the framework of the Thomas- Fermi approximation. The scattering length is a periodic function of the atomic number of the scattering atom. Both positive and negative scattering lengths are found. The effect of the sign and magnitude of the scattering length on the shape of the cross section vs. energy curve is studied. Atoms with negative scattering lengths are observed to have very low cross sections for some energy of the incoming electrons, but this is not the case for atoms having positive scattering lengths.
