Abstract
The differential scattering cross section (DCS) for electrons scattered elastically by neon is studied using a model potential. The short-range part of the effective potential is represented by the Chebyshev approximation and the long-range polarization potential is represented by an energy-dependent function. The computed differential cross section obtained using the approximate effective interaction potential for electrons scattered by neon atoms in their ground state in the 50–100 eV energy range is compared with available published results. In the present study, a nonrelativistic Hartree–Fock wave function of the target atom is used to compute the short-range static part of the interaction potential and the parameters contained in the energy-dependent function are determined by the minimization of the DCS with respect to the angle and the incident energy. The resulting DCS in the angular range 2°<θ<178° is found to be in good agreement with the available experimental and theoretical results in the intermediate energy range. © 1997 John Wiley & Sons, Inc.
