Effective Potential for e-Argon and e-Krypton Scattering by DCS Minimization at Intermediate Energies

摘要

The differential scattering cross section (DCS) for electrons scattered elastically by argon and krypton atoms is studied using a model potential. In the present study, the long-range polarization potential is represented by an energy-dependent function and the short-range part is constructed from the nonrelativistic Hartree-Fock wave function of the target atom. The computed differential cross section obtained using the approximate effective interaction potential for electrons scattered by neon and argon atoms in their ground state is compared with available published results. In the present study, the parameters contained in the energy-dependent effective potential are determined by the minimization of the DCS with respect to angle #theta# and the incident energy. The resulting DCS in the angular range 2 deg < #theta# < 178 deg is found to be in good agreement with the available experimental and theoretical results in the intermediate energy range.
