Relativistic effect in low-energy elastic scattering of electrons by inert-gas atoms
Grechukhin D. P., Lomonosov A. V.
Relativistic corrections must be made in a description of the elastic scattering of low-energy electrons by neon, argon, krypton, and xenon atoms. The interaction of an electron with an atom has been modeled by several spherically symmetric potentials. Numerical calculations have been carried out by the phase-function method and also through direct integration of the radial relativistic Dirac equation and the nonrelativistic Schrodinger equation. At energies below 1 eV, the difference between the values of the total cross section for the relativistic and nonrelativistic cases increases with increasing atomic number Z. © 1994 American Institute of Physics.
