摘要：

For the theoretical description of the multi-electron processes induced by charged particle impact we use a relatively simple perturbative method. The second-order approximation is valid for protons and antiprotons of moderate and high velocities. Electron correlation is taken into account by the use of configuration-interaction wavefunctions. The agreement with the available experimental data for some two-electron processes in the helium depends on the quality of the wavefunctions used. (C) 1999 Elsevier Science B.V. All rights reserved.
