摘要
Empirical scaling functions of the type suggested by Lee et al. [M.-T. Lee, I. Iga. L.E. Machado, L.M. Brescansin, E.A. y Castro, I.P. Sanches, G.L.C. Souza, J. Electron Spectrosc. Relat. Phenom. 155 (2007) 14] for the quasifree-scattering model are tested. The parameters of the scaling function have been fitted by using the genetic algorithm to reproduce the experimental data for the elastic scattering of electrons by helium, neon and argon atoms at impact energies 20-3000eV. The results confirm the effectiveness of the model. (C) 2008 Elsevier B.V. All rights reserved.
