摘要：

Several recently proposed modifications and improvements of the quasifree-scattering model for absorption potentials have been tested and compared. The possibility of obtaining energy-dependent polarization potentials from these absorption potentials by the dispersion relation is investigated. Numerical calculations for the elastic scattering of electrons by neon atoms at impact energies 20-3000eV are performed and the results are compared with experimental data. (C) 2007 Elsevier B.V.
